clk: qcom: gcc-sc7280: Update the .pwrsts for usb gdscs

The USB controllers on sc7280 do not retain the state when
the system goes into low power state and the GDSCs are
turned off. This results in the controllers reinitializing and
re-enumerating all the connected devices (resulting in additional
delay while coming out of suspend)
Fix this by updating the .pwrsts for the USB GDSCs so they only
transition to retention state in low power.
Since sc7280 only supports cx (parent of usb gdscs) Retention, there
are no cxcs offsets mentioned in order to support the Retention
state.

clk: qcom: gdsc: Fix the handling of PWRSTS_RET support

GDSCs cannot be transitioned into a Retention state in SW.
When either the RETAIN_MEM bit, or both the RETAIN_MEM and
RETAIN_PERIPH bits are set, and the GDSC is left ON, the HW
takes care of retaining the memory/logic for the domain when
the parent domain transitions to power collapse/power off state.

On some platforms where the parent domains lowest power state
itself is Retention, just leaving the GDSC in ON (without any
RETAIN_MEM/RETAIN_PERIPH bits being set) will also transition
it to Retention.

The existing logic handling the PWRSTS_RET seems to set the
RETAIN_MEM/RETAIN_PERIPH bits if the cxcs offsets are specified
but then explicitly turns the GDSC OFF as part of _gdsc_disable().
Fix that by leaving the GDSC in ON state.

clk: qcom: gcc-msm8909: Increase delay for USB PHY reset

The USB PHY on MSM8909 works with the driver used on MSM8916
(phy-qcom-usb-hs.c). When turning the PHY on/off it is first reset
using the standard reset controller API. On MSM8916 the reset is
provided by the USB driver (ci_hdrc_msm_por_reset() in ci_hdrc_msm.c).

While this seems to work on MSM8909 as well, the Qualcomm Linux sources
suggest that the PHY should be reset using the GCC_USB2_HS_PHY_ONLY_BCR
register instead. In general this is easy to set up in the device tree,
thanks to the standard reset controller API.

However, to conform to the specifications of the PHY the reset signal
should be asserted for at least 10 us. This is handled correctly on
MSM8916 in ci_hdrc_msm_por_reset(), but not within the GCC driver.

Fix this by making use of the new "udelay" field of qcom_reset_map
and set a delay of ~15 us between the assertion/deassertion of the
USB PHY reset signal.

clk: qcom: reset: Allow specifying custom reset delay

The amount of time required between asserting and deasserting the reset
signal can vary depending on the involved hardware component. Sometimes
1 us might not be enough and a larger delay is necessary to conform to
the specifications.

Usually this is worked around in the consuming drivers, by replacing
reset_control_reset() with a sequence of reset_control_assert(), waiting
for a custom delay, followed by reset_control_deassert().

However, in some cases the driver making use of the reset is generic and
can be used with different reset controllers. In this case the reset
time requirement is better handled directly by the reset controller
driver.

Make this possible by adding an "udelay" field to the qcom_reset_map
that allows setting a different reset delay (in microseconds).
