The bootsource ids reported by BootROM of RK3528 and RK3576 for e.g.
SPI NOR and USB differs slightly compared to prior SoCs:

- Booting from sfc0 (ROCK 4D) report the normal bootsource id 0x3.
- Booting from sfc1 M1 (NanoPi M5) report a new bootsource id 0x23.
- Booting from sfc1 M0 has not been tested (no board using this config).
- Booting from USB report a new bootsource id 0x81 on RK3528 and RK3576.

Add a helper function to read the bootsource id. This helper function
will be used to translate the new values to the common BROM_BOOTSOURCE
enum values on RK3528 and RK3576.

Update GMAC speed and flow control fields in GRF_SOC_CON1 to use
RK3288_GMAC_* prefix, ensuring a consistent naming convention. It also
shifts each mask/bit definition to match the actual hardware bits, which
makes future usage easier.

The current DT bindings for the rk3576 clock use a different ID than the
one that is supposed to be written to the hardware registers.
Thus, we cannot use directly the id provided in the phandle, but rather
use a lookup table to correctly setup the hardware.

This follows the implementation done in the Linux-Kernel and also
how the rk3588 does this both in the Linux-Kernel as well as U-Boot.

In the GRF header file, some instances of UART2 pinmux are prefixed with
"GRF_UART2DBG" while others have "GRF_UART2DGB".

Since UART2 is the default console UART and used for debugging, it is
more likely the name should be UART2DBG.

Fix the ones that are wrong.
