regmap: add MMIO bus support
This is a basic memory-mapped-IO bus for regmap. It has the following features and limitations: * Registers themselves may be 8, 16, 32, or 64-bit. 64-bit is only supported on 64-bit platforms. * Register offsets are limited to precisely 32-bit. * IO is performed using readl/writel, with no provision for using the __raw_readl or readl_relaxed variants.
