Based on the power sequence of the panel [1], the power on T2 sequence
VSP to VSN should be larger than 1ms, and the power off T2 sequence VSP
to VSN should be larger than 0ms. We modify the power sequence to meet
the datasheet requirement.

It is necessary to increase the AVDD/AVEE of TPS65132s PMIC to +-5.7V
for powering on BOE_TV110C9M_LL0. So we set the default value to +-5.7V
and program the value to the EEPROM when configuring the display at the
first time. In this way, TPS65132s could load the correct setting from
the EEPROM after booting into kernel.
BUG=b:268292556
TEST=test firmware display pass and AVDD/AVEE is +-5.7V on Geralt.
