mmc: sdhci-of-dwcmshc: Promote the th1520 reset handling to ip level

Browse source

commit 747528729c upstream.

Commit 27e8fe0da3 ("mmc: sdhci-of-dwcmshc: Prevent stale command
interrupt handling") clears pending interrupts when resetting
host->pending_reset to ensure no pending stale interrupts after
sdhci_threaded_irq restores interrupts. But this fix is only added for
th1520 platforms, in fact per my test, this issue exists on all
dwcmshc users, such as cv1800b, sg2002, and synaptics platforms.

So promote the above reset handling from th1520 to ip level. And keep
reset handling on rk, sg2042 and bf3 as is, until it's confirmed that
the same issue exists on these platforms too.
