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...
