Fixes gcc '-Wunused-but-set-variable' warnings:

drivers/power/supply/ab8500_charger.c:
 In function ab8500_charger_init_hw_registers:
drivers/power/supply/ab8500_charger.c:3013:24: warning:
 variable vbup33_vrtcn set but not used [-Wunused-but-set-variable]
drivers/power/supply/ab8500_charger.c:3013:5: warning:
 variable bup_vch_range set but not used [-Wunused-but-set-variable]

They are not used since commit 4c4268dc97c4 ("power:
supply: ab8500: Drop AB8540/9540 support")
