In case of error, the function devm_ioremap_resource() returns ERR_PTR()
and never returns NULL. The NULL test in the return value check should
be replaced with IS_ERR().

In case of error, the function of_phy_connect() returns NULL pointer not
ERR_PTR(). The IS_ERR() test in the return value check should be
replaced with NULL test.

Mostly whitespace cleanups. Some unneeded code was removed.
MMC init was also moved to the probe function as in
6069bdd087
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.

In some boards port 4 of mt7620 switch is powered down in bootloader
configuration as lan/wan package leak mitigation.
Reset ephy port 4 to default settings to power up the port.

The hardware emits some interrupts while initializing and handling them
can mess up the state or cause infinite loops.
Fix this by disabling IRQs during init and re-enabling them afterwards
