 exynos_srom_configure_bank(), is this name OK?

 Factoring out this loop is unnecessary, because i could just 'return 0' in the loop
instead of 'error = true'. Byt my idea is to go through all banks anyway, just in
case, to diagnose all of them. So that the user will be able to spot and fix all
broken banks at once, instead of doing one-by-one.
 I have renamed the variable to 'bool bad_bank_config', will this be OK?
