This series enables the CPU reset in the SPL for ZynqMP based platforms. This only works if CONFIG_SYSRESET is disabled. This is usually the case since the the regular sysreset requires bl31 firmware to be loaded in order to hand the sysreset over to PMU firmware. In SPL we can talk to the PMU firmware directly and request a CPU reset. The series also introduces SPL_ZYNQMP_FIRMWARE Kconfig symbol in order to make 'CONFIG_IS_ENABLED()' work in SPL.
