Add Realtek automotive PCIe driver

This series includes adding realtek automotive ethernet driver
and adding rtase ethernet driver entry in MAINTAINERS file.

This ethernet device driver for the PCIe interface of
Realtek Automotive Ethernet Switch,applicable to
RTL9054, RTL9068, RTL9072, RTL9075, RTL9068, RTL9071.

v1 -> v2:
- Remove redundent debug message.
- Modify coding rule.
- Remove other function codes not related to netdev.

v2 -> v3:
- Remove SR-IOV function - We will add the SR-IOV function together when
uploading the vf driver in the future.
- Remove other unnecessary code and macro.

v3 -> v4:
- Remove function prototype - Our driver does not use recursion, so we
have reordered the code and removed the function prototypes.
- Define macro precisely - Improve macro code readability to make the
source code cleaner.

v4 -> v5:
- Modify ethtool function - Remove some unnecessary code.
- Don't use inline function - Let the compiler decide.

v5 -> v6:
- Some old macro definitions have been removed and replaced with the
lastest usage.
- Replace s32 with int to ensure consistency.
- Clearly point out the objects of the service and remove unnecessary
struct.

v6 -> v7:
- Split this driver into multiple patches.
- Reorganize this driver code and remove redundant code to make this
driver more concise.

v7 -> v8:
- Add the function to calculate time mitigation and the function to
calculate packet number mitigation. Users can use these two functions
to calculate the reg value that needs to be set for the mitigation value
they want to set.
- This device is usually used in automotive embedded systems. The page
pool api will use more memory in receiving packets and requires more
verification, so we currently do not plan to use it in this patch.

v8 -> v9:
- Declare functions that are not extern as static functions and increase
the size of the character array named name in the rtase_int_vector struct
to correct the build warning noticed by the kernel test robot.
