power: supply: lp8788: Make several arrays static const * const
Don't populate various read only arrays on the stack but make them static const, making the object code smaller and saves 148 bytes overall: Before: text data bss dec hex filename 11940 4496 64 16500 4074 lp8788-charger.o After: text data bss dec hex filename 11472 4816 64 16352 3fe0 lp8788-charger.o Signed-off-by: Colin Ian King <colin.king@canonical.com> Signed-off-by: Sebastian Reichel <sebastian.reichel@collabora.co.uk>
