ramips: mtk-mmc: mt76x8: check ESD_MODE before applying AGPIO_CFG
Since mt76x8an ver1 eco2, SDXC pins can be switched to the
following pinmap:
sd_d1 -> PAD_I2S_SDI
sd_d0 -> PAD_I2S_WS
sd_cmd -> PAD_I2S_CLK
sd_d3 -> PAD_I2C_SCLK
sd_d2 -> PAD_I2C_SD
sd_clk -> PAD_GPIO0
sd_wp -> PAD_TXD1
sd_cd -> PAD_RXD1
To use this pinmap, one would need to set ESD_MODE bit (bit 15)
to 1 in GPIO1_MODE and switch other used pads into GPIO mode.
In this mode, we don't need to switch ethernet pins to digital
pad.
Check ESD_MODE bit before applying AGPIO_CFG and use rt_sysc_m32
to set it.
