serial: uniphier: set clock rate without clock-frequency property
In Linux, the clock rate of the UART is given by the clock driver. If you try to follow that in U-Boot, you would end up with adding more u-boot,dm-pre-reloc properties, and also the clock driver would be too big for SPL, which is used for UniPhier ARMv7 platform. The current solution is to add 'clock-frequency' property to the UART nodes, but it does not exist in the DT files in Linux. I do not want to let DT diverge for U-Boot. Check the SoC compatible and set the clock rate according to it. This will be helpful to sync DT between Linux and U-Boot. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
