BD9995X: Rename common code of BD99955 and BD99956 as BD9995X

Except the CHIP_ID and charger name code is common between BD99955
and BD99956. Hence renamed the code to BD9995X so that valid
output is printed from console commands.

BUG=chrome-os-partner:57519
BRANCH=none
TEST=Manually tested on Reef. 'charger' console command prints
     charger name as 'bd99956'
