watchdog: imx2_wdt: convert to use regmap API.
This watchdog driver will be working on IMX2+, Vybrid, LS1, LS2+ platforms, and will be in different endianness mode in those SoCs: SoCs CPU endian mode WDT endian mode ------------------------------------------------ IMX2+ LE LE Vybird LE LE LS1 LE BE LS2 LE LE Other possible SoCs: SoCs CPU endian mode WDT endian mode ------------------------------------------------ Soc1 BE BE Soc2 BE LE And also the watchdog's registers will be 32-bits for some versions, and though it is 16-bits in IMX2+, Vybird and LS+. Using the regmap APIs, could be more easy to support different endianness and also more easy to support 32-bits version...

This is the driver for the hardware watchdog
on the Freescale IMX2 and later processors.
