786367176d reset: uniphier: add SATA reset control support and change SATA-PHY ID
Add reset lines for SATA controller on UniPhier SoCs.
This adds support for Pro4 and PXs3 in addition to PXs2.

And this changes the ID of the reset line for SATA-PHY on PXs2.
Since some SoCs have two controller instances with a common PHY, this moves
the ID of SATA-PHY for consistency.

e6914365fd reset: uniphier: fix USB clock line for LD20
For LD20, the bit 5 of the offset 0x200c turned out to be a USB3
reset.  The hardware document says it is the GIO reset despite LD20
has no GIO bus, confusingly.

Also, fix confusing comments for PXs3.

dec173ccbc reset: uniphier: do not use per-SoC macro for system reset block
This macro turned out not so useful as I had expected.

Hardware engineers said they would change reset bit assignments for
every SoC going forward.  This means we can not share the macros
among SoCs.  Just use primitive macros.

88a7f5237d reset: uniphier: add compatible string for LD11 SD-reset block
The LD11 SoC is equipped with not only MIO-reset but also SD-reset
for controlling RST_n pin of the eMMC device.

Update the binding document and remove unneeded "." from each line
in itemization.

19eb4a4722 reset: uniphier: rename MIO reset to SD reset for Pro5, PXs2, LD20 SoCs
I made a mistake as for naming for this block.  The MIO block is not
implemented for these 3 SoCs in the first place.  The current naming
will be a trouble if an SoC with both MIO and SD-ctrl blocks appear
in the future.

This driver has just been merged in the previous merge window.
Rename it before the release.
