Item
Change chock
Cause NB_CORE and 1.1VALW efficiency measurement
result fail. so change inductor from 1.8uH to 1.0
uH, and change the tye from ferrite to moding

Change PL6 and PL8 from SH000009680 to
SH000009U00

Change resistance value
Cause change low side MOS from TPCA8028 to
AO4456. And there have different Rds(on). then
OCP will different, so i need to change ocp
setting resistance.

Change PR190 from SD000004100 (S RES 1/16W 8.2K
+-1% 0402) to SD00000QM80 (S RES 1/16W 14.3K
+-1% 0402)
