[ Upstream commit b072714bfc ]
Once regulators are disabled after kernel boot, on Espresso board silent
hang observed because of LDO7 being disabled. LDO7 actually provide
power to CPU cores and non-cpu blocks circuitries. Keep this regulator
always-on to fix this hang.

Add nodes for GPU (Mali T760) to Exynos7. Current support for Exynos7
misses a lot, including proper clocks, power domains, frequency and
voltage scaling and cooling. However this still can provide basic GPU
description. Not tested on HW.

'linux,stdout-path' has been deprecated for some time in favor of
'stdout-path'. Now dtc will warn on occurrences of 'linux,stdout-path'.
Search and replace the one occurrence with 'stdout-path'.

Usage of DTS macros instead of hard-coded numbers makes code easier to
read. One does not have to remember which value means pull-up/down or
specific driver strength.

Add RTC source clock as Exynos7 needs source (32.768KHz) clock
for RTC block. Without this currently S3C RTC driver probe is broken
on this SoC.

This patch enables HS200 mode operation on Exynos7 based
Espresso board.
This also removes _broken-cd_ property as per mmc binding documentation
which says one of the properties between broken-cd and non-removable
should be used. And we already use _non-removable_ as emmc is mounted
on the board which is a non-removable device.
