[U-Boot] [PATCH] Revert "imx: wdog: correct wcr register settings"

[Fabio Estevam]

From: Fabio Estevam <fabio.estevam at freescale.com>

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.
