[PATCH v2 5/7] arm64: dts: imx8mq-librem5: add power sequencing for M.2 cards

[Martin Kepplinger]

From: Angus Ainslie <angus@akkea.ca>

Some wifi cards need reset asserted until after the power supplies
have been enabled.

So wire up the W_DISABLE signal for the SDIO port (WIFI_REG_ON net) and
the BT_REG_ON net to use it for power sequencing.

[PATCH v2 6/7] arm64: dts: imx8mq-librem5: Limit the max sdio frequency

[Martin Kepplinger]

From: Angus Ainslie <angus@akkea.ca>

This is needed for the 1LV Cyress WiFi module to probe correctly.
It also helps improve GNSS sensitivity.
