chipidea: usbmisc_imx: Allow USB OTG to work on mx51
The field PLLDIVVALUE of register PHY_CTRL_1 selects the reference clock source
for the PHY:
00 = sysclock uses 19.2 MHz
01 = sysclock uses 24 MHz
10 = sysclock uses 26 MHz
11 = sysclock uses 27 MHz
The reset value for this field is 10 according to the reference manual, and

set it to 01 so that a 24MHz clock can be selected for the PHY and allowing both

Feedback from David Miller [1] was to remove this function instead of making it
static:
"Please just delete this function.
It's overriding code which does exactly the same thing.
Actually, more precisely, this code is duplicating code in a way that
bypasses many core facilitites of the networking. For example, this
override means that socket based flow steering, XPS, etc. are all
not happening on these devices.
Without ->ndo_select_queue(), the flow dissector does __netdev_pick_tx
which is exactly what you want to happen."
Commit 63288b721a80 ("ARM: imx: fix shared gate clock") attempted to fix
an issue with particular enable/disable sequence from two shared gate
clocks. But unfortunately, while it partially fixed the issue, it also
did something wrong in .is_enabled() function hook. In case of shared
gate, the function shouldn't really query the hardware state via
share_count, because the function is trying to query the enabling state
of the clock in question, not the hardware state which is shared by
multiple clocks.
Fix the issue by returning the enable_count of the clock itself which is
maintained by clock core, in case it's a clock sharing hardware gate
with others. As the result, the initialization of share_count per
hardware state is not needed now. So remove it.
