drivers: mipi: Fine tune STA_ILI9882T panel HBP and HFP

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
