To remove unnecessary if statements, this patch introduces phy_enable
and phy_disable callbacks in driver data structure that implement
SoC-specific PHY initialization and deinitialization.

This patch cleans up handling of reference clock rate in Samsung USB PHY

There is no need to use devm_clk_get to get a clock that is being put

Since phy-samsung-usb library can be used only by phy-samsung-usb2 and
phy-samsung-usb3 drivers, there is no need to give explicit control over
its Kconfig symbol.

This patch makes CONFIG_SAMSUNG_USBPHY symbol hidden and selected
implicitly by CONFIG_SAMSUNG_USB2PHY and CONFIG_SAMSUNG_USB3PHY.

The driver supports both ab8500 and ab8505, but the actual phy tuning
values logic sets ab8500 values:

if (!is_ab8500_2p0_or_earlier(ab->ab8500))

which is supposed to set values for ab8500, but incorrectly results true
for ab8505 too.

Fix this by adding an additional is_ab8500(ab->ab8500) check.

The musb struct is currently allocated along with the hcd, which makes
it difficult to build a driver that only acts as gadget device.

Fix this by allocating musb directly, and keep the hcd around as
a pointer in the musb struct.

struct hc_driver musb_hc_driver can now also be static to musb_host.c,
and the macro musb_to_hcd() is just a pointer dereferencer for now, and
will be eliminated later.

do_smart_update_queue() is called when an operation (semop,
semctl(SETVAL), semctl(SETALL), ...) modified the array.  It must check
which of the sleeping tasks can proceed.

do_smart_update_queue() missed a few wakeups:
 - if a sleeping complex op was completed, then all per-semaphore queues
   must be scanned - not only those that were modified by *sops
 - if a sleeping simple op proceeded, then the global queue must be
   scanned again

And:
 - the test for "|sops == NULL) before scanning the global queue is not
   required: If the global queue is empty, then it doesn't need to be
   scanned - regardless of the reason for calling do_smart_update_queue()

The patch is not optimized, i.e.  even completing a wait-for-zero
operation causes a rescan.  This is done to keep the patch as simple as
possible.
