Subject: [PATCH] arm64: dts: imx8qm-mek: fix mux-controller select/enable-gpios polarity

According to the board design, set SEL to high means flipped
connection (TX2/RX2). And the TCPM will output logical 1 if it needs
flipped connection. So switch to active high for select-gpios.
The EN pin on mux chip is low active, so switch to active low for
enable-gpios too.
