Regmap already provides us with the caching, so remove caching of charger
state to make code cleaner.

cache_type is not initialized in smb347's regmap config and thus
set to 0 = REGCACHE_NONE:

static const struct regmap_config smb347_regmap = {
	.reg_bits	= 8,
	.val_bits	= 8,
	.max_register	= SMB347_MAX_REGISTER,
	.volatile_reg	= smb347_volatile_reg,
	.readable_reg	= smb347_readable_reg,
};

Good catch, thank you. I'll add patch to enable caching.
