pcm058: Fix unused variable warnings

The variable nfc_pads is only referenced when CONFIG_CMD_NAND is set,
add a gaurd.  The variable gpio_pads is never referenced, drop it.  The
variable usdhc4_pads are only referenced when we do not have
CONFIG_CMD_NAND set and we are not doing an SPL build, modify the
existing guard.
