[OFW] io ranges use ptr array to storage without ofw data
ofw data is private data for every ofw node that
the drivers of ofw node will use item.
replace the ranges supported to a ptr array.
the ptr array size is config by `RT_USING_OFW_BUS_RANGES_NUMBER`

* [PIC/GIC] Fixup GIC affinity init
GICv2 is not support if current CPU is not startup,
but RT-Thread SMP is startup after the devices init
in the `main` thread.
This patch fixup the cpumask to init once and check
the init status in affinity interface.

DFS mount auto by kernel parameters
1.Mount the rootfs options by parameters:
- root=: root device, like vda1, sda1, sd0p1, nvme0n0p1...
- rootfstype=: root file system type, like elm, ext, crom...
- rw/ro: root is readonly or all enable, if not have 'rw' flag,
the 'ro' flag is default.
- rootwait: always wait for root device status is OK.
- rootdelay=: mount rootfs delay amount of time (millisecond).
2.Mount the other fs options by `fstab.sh`, it will read the script
after root mount is OK, it's format is a list of mount cmds in MSH:
mount vda2 /mnt elm
mount 192.168.1.1:/ /mnt/remote nfs

This change addresses a potential out-of-memory access issue in the
devfs filesystem component. The issue arises when the `rt_malloc`
function allocates memory for a path string without accounting for
the null terminator, leading to undefined behavior.
As the manual documented:
> DESCRIPTION
> The strlen() function calculates the length of the string pointed to
> by s, excluding the terminating null byte ('\0').
To fix this, the memory allocation size was increased by one byte
to ensure space for the null terminator. This prevents potential
out-of-memory access and ensures proper string termination.

* [thread] Add rt_thread_close()
This patch introduces a new function `rt_thread_close()` to enhances the
usability and maintainability by providing a dedicated mechanism for
closing threads.
- A new function `rt_thread_close()` is added to the API, providing a
standardized approach for closing threads.
- The `rt_thread_close()` function removes a thread from the thread
queue, updates its status to indicate closure, and performs the thread
timer detaching which is a embedded timer in thread object.
- Additionally, the `rt_thread_detach()` function is modified to utilize
`rt_thread_close()` internally, streamlining the thread detachment
process.
