IPAv2 hardware works with 32 bit addressing,
so allocate a kernel memory using GFP_DMA flag
which is processed by IPA hardware.

Fix the compilation errors and add error logging for
memory allocation failures.
Also change the driver init level to fs_initcall as
clock driver is probed at subsys_initcall level.

When a low hysteresis for thresholds are set there is a
possibility that low and high thresholds are crossed at
around the same time before the client is notified. Under
such condition there could be a low and high interrupt
received before processing the request and notifying the
client. Check the return value for queued item for
notifying the client and reduce the count used to prevent
suspend if the item is already available in the global queue.

Currently TRB buffer is allocated using gadget->dev.parent node
(e.g a600000.dwc3) instead of device node (e.g a600000.ssusb)
which is used to create IOMMU based context bank. Hence use
gadget->dev.parent->parent to allocate buffer to avoid unmapped
SMMU page fault while enabling USB SMMU stage S1 functionality.

The delay argument in schedule_delayed_work(struct delayed_work
*dwork, unsigned long delay) API is jiffies. The system tick for
seems to be 100Hz, so the minimum time resolution for the work to
be scheduled is 10ms.

Switch to hrtimer to achieve 3 ms granularity with a current timer
of 1ms for the flush thread. A workqueue is immediately scheduled
in the same context after this timer expiry to do the tx work.

In case of an exception, there could be a deadlock:

eeh_work:
-002|schedule()
-003|spin_lock_irq()
-003|rpm_resume << pm_runtime_get_sync(hba->dev);
-004|__pm_runtime_resume()
-005|ufshcd_scsi_block_requests()
-005|ufshcd_exception_event_handler()

ufshcd_suspend:
-002|schedule()
-003|schedule_timeout()
-004|do_wait_for_common()
-004|__wait_for_common()
-004|wait_for_common()
-005|wait_for_completion()
-006|destroy_work_on_stack()
-006|flush_work(?) << eeh_work
-007|ufshcd_suspend()
-008|ufshcd_runtime_suspend()
-009|ufshcd_pltfrm_runtime_suspend()
-010|pm_generic_runtime_suspend()
-011|__rpm_callback()

Scenario looks like :
1.Hba->eeh_work starts to work and at the almost same
time ufshcd_runtime_suspend start to work by rpm core.
2.pm_runtime_get_sync in eeh_work remains pending as
rpm_status is RPM_SUSPENDING due to ufshcd_runtime_suspend.

To fix this, call pm_runtime_get_noresume() once eeh_work
is scheduled so that suspend cannot be invoked during
exception work.
