After first called from uart open, the dw8250_uart_configure
API cannot be called again. Otherwise, this will mess up the
device, and uart will not act properly to interrupt again.
Analysis: Configure uart device will close recive interrupte,
causing uart device to malfunction.
Solution: After configure uart device, enable the device's
recive interrupte.

Analysis: The IRQ_MAX_NR value of c906_little is wrong.
interrupt.h relies on IRQ_MAX_NR defined in rtconfig.h but
does not explicitly include this header file.
Solution: Change IRQ_MAX_NR to the correct value 61 in
the datasheet. Explicitly include rtconfig.h in interrupt.h.

The aarch64 core of duo on the master cannot enter the
console interface. It can only print the RT flag and hold it.
Analysis: The latest commit that can work is ae6a328 ("Add
psoc62, 61 config"). This phenomenon will occur after adding
754c59a ("[Feature] DFS mount auto by kernel parameters").
The specific reason is that when aarch bsp enables the device
tree, the current u-boot will pass in bootargs, which contains
"root=/dev/mmcblk0p2 rootwait rw", which means that the
kernel is required to wait until the rootfs in /dev/mmcblk0p2
loaded successfully. However, the current aarch64 bsp default
does not implement sdmmc device mounting, causing the
kernel file system mounting module (rootfs_mnt_init() of
components/drivers/core/mnt.c) to enter an infinite loop waiting.
Solution: At present, we do not plan to modify the startup
parameters of u-boot. The temporary solution adopted is to
create a pseudo /dev/mmcblk0p2 device during the board
initialization process, and then cancel the pseudo device
after mnt is completed. This allows the kernel boot to be
completed successfully.

In the original Sconstruct script, `GetDepend('__STACKSIZE__')`
is placed before the call to `PrepareBuilding()`, which causes
the value of `GetDepend('__STACKSIZE__')` to always be False,
and the value of `__STACKSIZE__` in `link_stacksize.lds` will
not be updated.
Solution: move the call if `PrepareBuilding()` ahead.
Also sync and update the .config and rtconfig.h, plus the
link_stacksize.lds.

Currently, the documents under bsp/cvitek are a bit
messy. There are currently four readme files:
- bsp/cvitek/README.md (Chinese)
- bsp/cvitek/c906_little/README.md (Chinese/English)
- bsp/cvitek/cv18xx_aarch64/README.md (Chinese)
- bsp/cvitek/cv18xx_risc-v/README.md (Chinese/English)
Regarding the working mode of the big + small cores, it
is meaningless to describe the small core alone, or the
large core alone. This can also be seen in the existing
files. The readme of the small core will also introduce
the programming of the large core, and vice versa.
Considering that the official default mode is
C906B + C906L. ARM large core can be treataed as a
special case. So the document structure is modified as
follows:
- Remove `bsp/cvitek/c906_little/README.md` and
`bsp/cvitek/cv18xx_risc-v/README.md`, merge them all
into `bsp/cvitek/README.md`
- Add a link to `bsp/cvitek/cv18xx_aarch64/README.md`
in `bsp/cvitek/README.md`

In the new design, we require the user to manually enter the
PinName (as a string) in menuconfig instead of being given
menu items to select.
The original method will lead to too many menu item-related
macros being defined in the code, causing ifdef and other
codes scatter everywhere in the driver code, which is
inconvenient to maintain.
The new design adds a pinmux driver module to manage the
multiplexing of pins. This patch provides this driver module.
P.S., the reason why users are allowed to specify pinname
in a string instead of the pin number is mainly because
the technical manual provided by the SOC manufacturer
does not have numbers for some pins, only names.

- Initialized riscv timer on `rt_hw_tick_init`
- Refactored `tick.c` and `tick.h` in `libcpu/risc-v/t-head/c906` and `libcpu/risc-v/virt64`:
- Replaced direct use of `rdtime` with `clock_cpu_gettime`.
- Removed redundant timer frequency definitions.
- Added static assertions to check the value of `CPUTIME_TIMER_FREQ`.
- Initialized `tick_cycles` based on `CPUTIME_TIMER_FREQ`.
- Integrated `ktime` support for tick initialization.
