[PATCH AUTOSEL 5.15 02/14] mmc: core: Respect quirk_max_rate for non-UHS SDIO card

[Sasha Levin <sashal@kernel.org>]

From: Shawn Lin <shawn.lin@rock-chips.com>

[ Upstream commit a2a44f8da29352f76c99c6904ee652911b8dc7dd ]

The card-quirk was added to limit the clock-rate for a card with UHS-mode
support, although let's respect the quirk for non-UHS mode too, to make the
behaviour consistent.
