The Trogdor Homestar DTSI adds additional GPIO52 pin to secondary I2S pins
("sec_mi2s_active") and configures it to "mi2s_1" function.
The Trogdor DTSI (which is included by Homestar) configures drive
strength and bias for all "sec_mi2s_active" pins, thus the intention was
to apply this configuration also to GPIO52 on Homestar.
