[PATCH v9 07/12] mach-snapdragon: Kconfig: changes / additions to support SPL

[michael.srba at seznam.cz]

From: Michael Srba <Michael.Srba at seznam.cz>

Select SUPPORT_SPL so SPL build can be enabled, disable SYSRESET_PSCI in SPL.
(SPL runs in EL3, so if SPL itself doesn't provide PSCI, nothing else will.)

Also select (SPL_)OF_LIVE and (SPL_)EVENT, which are needed to fix up
upstream dt to make usb work, and in general don't make sense to
disable in SPL as long as we're not running out of SRAM.

Mirror u-boot proper selections like GPIO and pinctrl to ensure consistent
behavior, and select SPL_SPRINTF, SPL_LIBCOMMON_SUPPORT etc for similar
reasons.
