The reverted patch is to workaround a hang issue which is caused
by DCSS reset control bug in 'Block Control' submodule. But this

Since the USB Type-C port only has two data roles, host and device,
the controller driver can only receive above two events, it can't
remain 'disconnection' state alone at controller driver due to there
is no such event from Type-C.
Due to above, we delete the controller state "CDNS3_ROLE_END" which
stands for 'disconnection' state before. Instead, when we use
"CDNS3_ROLE_GADGET" stands for it, and this state is the default
state for controller.

On some i.MX8MQ-EVK A0/A1 board, we may meet eMMC read data CRC error in
HS400 mode. This is because the delay cell set for the strobe pad
is not correct. Before this patch, usdhc driver default set this delay
cell to value 7, but for some board, only value 3~6 can pass read
operation in HS400 mode, some board, the pass value is 2~10, and
some board, the pass value is 3~8. So the default value 7 can't
make sure all the board can pass eMMC read in HS400.
This patch set the value 5 to fsl,strobe-dll-delay-target, make sure
all the board can work stable in HS400 mode.

The current clk_mux_set_parent_scu() implementation returns error
if device power domain is not enabled. As consequence of this the
existing "assigned-clock-parents" DTS functionality cannot be used for
clk_mux. In order to avoid returning error in "set_parent" the code is
refactored as follows:
a) On "set_parent" the "mux->reg" value is prepared and stored in
"mux->val" field. The "mux->reg" is updated if power domain is enabled,
or triggered for update on "prepare" subsequent call otherwise.
b) On "prepare" the power domain status check is performed and "mux->val"
is stored in "mux->reg" if triggered for update.
c) On "get_parent" the "mux->reg" is not read anymore and "mux->val" is
used to get the "get_parent" output.
