caa332336d mmc: mtk-sd: add WATCHDOG_RESET() to prevent watchdog timeout
When reading large data in once (reading 512MiB is tested on MT7623), a
watchdog timeout is triggered due to watchdog not being fed.

This patch adds WATCHDOG_RESET() to msdc_start_data() so the watchdog will
be fed every 1024 blocks are read/written.

b5096f1b6d mmc: mtk-sd: fix configuration option check
We either need to use IS_ENABLED(CONFIG_FOO) or CONFIG_IS_ENABLED(FOO).
IS_ENABLE(FOO) will always return false.

This commit fixes the comparison by using the CONFIG_IS_ENABLED(FOO)
syntax.

ba077e5f74 mmc: mtk-sd: add source_cg clock support
Some MediaTek SoC need an additional clock "source_cg". Enable
this new clock. We reuse the same clock name as in the kernel.

70dbbd7269 mmc: mtk-sd: fix SPL compilation when GPIO=y and SPL_GPIO=n
It is not possible to link the SPL image when CONFIG_GPIO is enabled
but CONFIG_SPL_GPIO is not.  Use the IS_ENABLED macro instead to
correctly check whether CONFIG_{SPL_}GPIO is enabled.

This commit fixes the following errors:
	* undefined reference to `dm_gpio_get_value
	* undefined reference to `gpio_request_by_name'

924ed344a7 mmc: mtk-sd: fix possible incomplete read ops
The code is checking for incomplete read when it see the INT_XFER_COMPL
flag, but it forget to first check whether there is anything left in the
FIFO to copy to the RX buffer. This means that sometimes we will get
errors because of erroneous incomplete read operation.

This commit fixes the driver re-ordering the code so that we first
check for data inside the RX fifo and only after check the status
of the INT_XFER_COMPL flag.
