arm64: zynqmp: Do not setup default SPL options without SPL

mach Kconfig file select some options independently of if SPL is actually
enabled. It ends up in situation that SPL is disabled but symbols are still
present in .config. That's why add SPL dependency for them but also group
them with other SPL options in ARCH_ZYNQMP fragment with using imply
option. This should ensure the same behavior as default y.

Also fixed SPL_ZYNQMP_PSU_INIT_ENABLED for the same.
