Except spi2m2 which is used for pmic. all spi change from 33ohm to 40ohm
to avoid overcharge.

There is a bug in the HDMI controller DDC. The falling edge of
SDA and SCL almost coincide and cannot be adjusted, resulting
in poor compatibility of DDC. The compatibility of DDC can be
improved by increasing the driver strength of SCL and decreasing
the driver strength of SDA to increase the slope of the falling edge.

RK806 INT pin is connected to pmic_int(gpio0a7).
the pmic_int sets low-level interrupt, which requires pull-up
voltage(VCC_1V8_S0). but the pull-up voltage is powered off
in system suspend, causing the system to wake up immediately.

1.The EVB signal test of this configuration is good.
2.This confitguration is compatible with 16MHz and 50MHz SI test case.
