regmap: Add bypassed version of regmap_multi_reg_write
Devices with more complex boot proceedures may occasionally apply the register patch manual. regmap_multi_reg_write is a logical way to do so, however the patch must be applied with cache bypass on, such that it doesn't override any user settings. This patch adds a regmap_multi_reg_write_bypassed function that applies a set of writes with the bypass enabled.
