clk: qcom: gcc-sm8450: Add SM8475 support

Add support to the SM8475 global clock controller by extending the
SM8450 global clock controller, which is almost identical but has some
minor differences.

 	  Say Y if you want to use peripheral devices such as UART,
 	  SPI, I2C, USB, SD/UFS, PCIe etc.
