power: supply: adp5061: fix out-of-bounds read in adp5061_get_chg_type()

[ Upstream commit 9d47e01b9d807808224347935562f7043a358054 ]

ADP5061_CHG_STATUS_1_CHG_STATUS is masked with 0x07, which means a length
of 8, but adp5061_chg_type array size is 4, may end up reading 4 elements
beyond the end of the adp5061_chg_type[] array.
