* [DM/FEATURE] Support reset controller
Reset controllers are central units that control
the reset signals to multiple peripherals.
The reset controller API is split into two parts:
1. The consumer driver interface, which allows
peripheral drivers to request control over
their reset input signals
2. The reset controller driver interface
which is used by drivers for reset controller devices to
register their reset controls to provide them to the consumers.
* [RESET/SIMPLE] Support simple reset
Currently this driver supports:
- Altera SoCFPGAs
- ASPEED BMC SoCs
- Bitmain BM1880 SoC
- Realtek SoCs
- RCC reset controller in STM32 MCUs
- Allwinner SoCs
- SiFive FU740 SoCs
- Sophgo SoCs

This framework will be of use only to devices that use
external PHY (PHY functionality is not embedded within the controller).
Use in PCIE, USB, HDMI, DP...

* [DM/FEATURE] Support NVME
1. Support PRP and SGL (>= NVME v1.1) transport.
2. Support MSI/MSI-X for IO queues.
3. Support NVME on PCI.

Open Kconfig will not fail if using osource,
This way can make SoC Kconfig to DM easy.

1. Default return OK when input NULL (if is not necessary in device).
2. Support object parse in OFW.
3. Support CLK depends fix auto.
4. Fixup rt_clk_array_prepare_enable and rt_clk_array_disable_unprepare.

old phy bus is too simple add phy_bus is not adapt rt_bus framework,so writer a stronger phy bus framework.
here is my commit message:
add mdio bus and phy bus to kernel,the phy bus use rt_bus framewok ,driver writer can write phy_driver first .when mac driver need to use phy they can register phy_device and pjhy_devie will serach for driver which match by uid and mask,if no driver match with the device that you register,phy_bus will return the genphy to you device,the genphy driver is the general driver for phy,so you can use it but it can not support the capcity of chip it may be cause performance is not up to peak
We need a API to fix the driver load auto when
a second driver get it in probe process that
we can not be careful of the driver-to-driver's
depends in different SoC.

Drivers can manage their own IDs without having to concern
themselves with the register/unregister in system

POSIX.1 says:
> read() attempts to read up to count bytes from file descriptor fd
> into the buffer starting at buf.
On the other hand, for rt_device_read, the `@size` is defined as the
number of unit (block size for blk device, otherwise one byte).
Changes:
- Transferred unit size from POSIX R/W(in bytes) to rt_device_R/W during
request of file R/W operations.

The `struct stat` object used inside mount(2) is uninitialized, which
can lead to undefined behavior during running
Changes:
- Set zero to buffer before calling to stat()
