[PATCH] mmc: meson-gx: increase power-up delay

[Marc Gonzalez]

With the default power-up delay, on small kernels, the host probes
too soon, and mmc_send_io_op_cond() times out.

Stress-tested with 80 cold boots, checking every time
mmc2: new ultra high speed SDR50 SDIO card at address 0001
IIUC, this will also slow down SD & MMC probing,
but an additional 20 ms seems acceptable?
