With MMC_PWRSEQ enabled the following link issue may happen when building SPL and SPL_PWRSEQ is not enabled.

aarch64-linux-gnu-ld.bfd: drivers/mmc/meson_gx_mmc.o: in function `meson_mmc_probe': drivers/mmc/meson_gx_mmc.c:295: undefined reference to `pwrseq_set_power'

Fix this by adding a SPL_MMC_PWRSEQ Kconfig option used to enable mmc pwrseq support in SPL.

Also add depends on DM_GPIO to fix following link issue:

Applied to u-boot-mmc/master, thanks! Sorry for late.
