For CMD21 tuning data, the 128/64 bytes data may coming in very
short time, before msdc_start_data(), the read data has already
come, in this case, clear MSDC_INT will cause the interrupt disappear
and lead to the thread hang.

the solution is just clear all interrupts before command was sent.

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.

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.

Some MediaTek SoC need an additional clock "source_cg". Enable
this new clock. We reuse the same clock name as in the kernel.

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'

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.
