[PATCH] drivers: firmware: psci: Use __pa_symbol for cpu_resume

[Geert Uytterhoeven]

If CONFIG_DEBUG_VIRTUAL=y, during s2ram:

    virt_to_phys used for non-linear address: ffffff80085db280 (cpu_resume+0x0/0x20)
    ------------[ cut here ]------------
    WARNING: CPU: 0 PID: 1628 at arch/arm64/mm/physaddr.c:14 __virt_to_phys+0x28/0x60
    ...
    [<ffffff800809abb4>] __virt_to_phys+0x28/0x60
    [<ffffff80084a0c38>] psci_system_suspend+0x20/0x44
