This reverts commit 623d96e89aca64c2762150087f4e872c55481f13.
commit 623d96e89aca6("imx: wdog: correct wcr register settings")
introduced the usage of clrsetbits_le16(), which causes a regression
on LS1021 systems.
Unlike i.MX, LS1021 uses big-endian ordering for the watchdog
controller, which means we cannot use the little endian accessors.
