[PATCH 1/2] ARM: imx_v6_v7_defconfig: Enable RTC PCF8523 support

[Fabio Estevam]

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

RTC PCF8523 is used on some mx6 cubox-i boards.

Let it work by default.

[PATCH 2/2] ARM: dts: imx6q-cubox-i: Disable the internal RTC

[Fabio Estevam]

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

The internal SNVS RTC on imx6q-cubox-i is not battery backed and there
is a PCF8523 that is battery backed on CuBox-i2eX and CuBox-i4Pro models.

Disable the internal RTC in favour of the battery backed one, so that
we can have a valid clock setting right after boot.
