In the datasheet of ILI9882T [1] section 3.11 Power On/Off Sequence,
the TReset-CMD (Reset to First Command in Display Sleep In Mode) should
be larger than 10ms, but it's 1.1ms now. This may cause abnormal
display as some commands may be lost during power on. Fix this and
leave some margins by increasing TReset-CMD to 20ms. Also, to align
with the kernel driver structure starry_ili9882t_init_cmd, add 20ms
delay at the end of command.

coreboot logs the error below, since the value of hporch is too small. Increasing hbl from 80 to 174, and hso from 40 to 72 to revise the HBP(Horizontal Back Porch) and HFP(Horizontal Front Porch). After revising this, the actual measurement frame rate is 60.1Hz.
[ERROR]HFP plus HBP is not greater than d_phy, the panel may not work
properly.
BUG=b:284812193
TEST=cbmem -c | grep "ERROR" and measure frame rate
