mfd: madera: Don't use regmap_read_poll_timeout to poll for BOOT_DONE
While polling for BOOT_DONE the chip could NAK a read because it is
still booting, which would terminate the regmap_read_poll_timeout()
with an error.
Instead implement a polling loop that ignores read errors so we
always poll until the chip signals boot or the loop times out.
