Some boards use another WDOG reset source to reboot system in ldo-bypass mode.
We need add the property in board dts file so that we can easily know the
WDOG reset source currently.
For Sabresd, WDOG1 for ldo-enable mode(WDOG event), WDOG2 for ldo-bypass mode
(reset external pmic to trigger POR event).
For sl-evk board, there is no WDOG pin connected with external pmic as Sabresd
, because mx6sl boot at 400Mhz. Then both ldo-enable and ldo-bypass mode use
the common WDOG1 as reset source.

Currently, we use different dts files to support ldo-bypass or ldo-enable, then
we need add both dts files for the boards which can support ldo-bypass mode(all
boards support ldo-enable at least). So for below boards we need add ldo-enable
dts file so that we can use this to easily support ldo-enable mode:
1)mx6q-sabresd board: ldo-bypass dts->mx6q-sabresd.dtb,
ldo-enable dts->mx6q-sabresd-ldo.dtb
2)mx6q-sabresd board: ldo-bypass dts->mx6dl-sabresd.dtb,
ldo-enable dts->mx6dl-sabresd-ldo.dtb
3)mx6sl-evk board: ldo-bypass dts->mx6sl-evk.dtb,
ldo-enable dts->mx6sl-evk-ldo.dtb
