cam: support volt compatible for hm2sp03&hm2sd03

Browse source 
-On xpeng,rear main camera s5khm2 will have two type(SP03&SD03), we need
set correct DVDD voltage for each sensor per module pin_20 value.
-Use gpio_48 to read module pin_20
-1 means hm2SP03,DVDD is 1.1v. 0 means hm2SD03,DVDD is 1.05v.
