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.

The pinmux for all SoCs using this driver is now set via the pinmux. It
makes this code obsolete.
Some of the code targeting the mt76x8 SoCs is still required. The sd
card pins share the pads with the EPHY. These pads need to be switched
to digital mode if the pins are used for sd cards.
The eMMC 8-bit mode has to be enabled via pinmux instead of a kernel
option. The uart2 group need to be set to function "sdxc d5 d4", pwm1
to "sdxc d6" and pwm0 to "sdxc d7" to do so. It can't be done by as
part of a default pinmux, as it would break the normal operation of
uart2.

This reverts commit 3a8efaef00.
The change reportedly breaks UART2 on some boards. Furthermore it uses
bitwise logic on an uninitialized variable and fails to explain what it
is fixing exactly.

There is another thing about crc to do when initialize SD card on
MT7628.
This commit is to fix this init issue.

This reverts commit 8a570921b5.
This seems to have been accidentally reverted. This fixes mt7620 and
mt7628.

Mostly whitespace cleanups. Some unneeded code was removed.
MMC init was also moved to the probe function as in
6069bdd
The cleanup commits are over 100, making it hard to do them individually.
Tested on GnuBee PC1 with an SD card being used as swap.

of_dma_configure() sets a default ->dma_mask of
DMA_BIT_MASK(32), claiming devices can DMA from
the full 32bit address space.
The mtk-mmc driver does not support access to
highmem pages, so it is really limited to the
bottom 512M (actually 448M due to 64M of IO space).
Setting ->dma_mask to NULL causes mmc_setup_queue()
to fall-back to using BLK_BOUNCE_HIGH to tell the
block layer to use a bounce-buffer for any highmem
pages requiring IO.

Our .dts files only have one device defined and this is unlikely to
change, so statically initialize host->id to 0.
