Add a clock-frequency property to set the rate of io clock, according to various host controller mode it require different initial clock frequency, and also match to the board's layout actually validated at.

Introduce a vendor specific property to configure the step count of TX delay line which should be applied before RX tuning, compensating for board level trace differences. The TX delay line result comes from test out of real board which vary from different hardware layout.

Add a clock-frequency property to set the rate of io clock, for SDIO case, a clock frequency need to propagate down early. Signed-off-by: Long Wan <long.wan@linux.spacemit.com> Signed-off-by: Yixun Lan <dlan@kernel.org> Signed-off-by: Linux RISC-V bot <linux.riscv.bot@gmail.com>
Instead of setting the TX delay code via hardcoded parameter, configuring it via device tree property, which make it able to adapt according to board specific tuning requirement.
