The default phase can meet most cards' requirement, but it is not the
optimal one. In some extreme situation, the rx phase point produced by
the following tuning process will drift quite a distance.
Before tuning UHS card, this patch will set a more proper initial tx
phase point, which is calculated from statistic data, and can achieve
a much better tx signal quality.

1. Add a function rtsx_pci_power_off to abstract the common ops in

2. Add pcr->ops->force_power_down to fulfill the individual action for

Since the TWL6030 PMIC is used with OMAP4 SoCs only and OMAP4 legacy
boot is dropped there are no needs to allocate the range of IRQ
descriptors during system boot to support TWL6030 IRQs.

Hence, convert it to use linear irq_domain and move IRQ configuration in
.map()/.unmap() callbacks of irq_domain. So, IRQ mapping and descriptors
allocation will be performed dynamically basing on DT configuration.

The error message will be reported in case if unmapped IRQ is received by
TWL6030 (virq==0).

1) Removed request_irq() and replaced it with request_threaded_irq().

2) Removed generic_handle_irq() and replaced it with
handle_nested_irq().
  Handling of these interrupts is nested, as we are handling an
interrupt (for e.g rtc, mmc1) when we are still servicing TWL irq.

3) Removed I2C read-retry logic for the case when twl_i2c_read() is
failed inside IRQ handler - there is no sense to do that, so just report
an error and return.

4) Each nested IRQ is configured with corresponding parent_irq,
which need to be retriggered in case if nested IRQ is marked
as IRQS_PENDING.

regmap: Support for acknowledging masked IRQs

Some devices need interrupts to be clear when they are masked otherwise
the interrupt is not deasserted by the mask being set - add support for
this to regmap-irq from Philipp Zabel.

The reg_cache variable should be updated with current
steps in the reg_se register. Then the mask should
apply and clear the register. Previously, the reg_cache
can be an old redundant value that isn't updated.
