This patch adds support for resetting a board via the RAA215300 PMIC.
Note that the RAA215300 documentation names the available reset types
differently to u-boot:
* A "warm" reset via the RAA215300 PMIC will fully reset the SoC
(CPU & GPIOs), so this corresponds to SYSRESET_COLD.
* A "cold" reset via the RAA215300 PMIC will cycle all power supply
rails, so this corresponds to SYSRESET_POWER.

The RZ/G2L SMARC module is powered via a Renesas RAA215300 PMIC which
provides several voltage converters, a real time clock (RTC) and reset
control. A basic driver is implemented for this device so that we can
read, write and dump the PMIC registers.
The raa215300_bind() function is added as a stub, binding of the
sysreset driver will be added in a later patch.
Additional features of this PMIC (such as reset control) may be
supported by future patches.

This driver supports the I2C module on the Renesas RZ/G2L (R9A07G044)
SoC, also known as the RIIC module.
This patch is based on both the u-boot driver in the Renesas RZ BSP
3.0.5 release [1] (commit 7fcc1fdc2534), and the Linux v6.7 driver
(commit 0dd3ee311255).
Support for deblocking the I2C bus is included as this may be needed
after triggering a reset via the Power Management IC (PMIC) over I2C
(the PMIC asserts the reset line before the SoC completes the I2C write
transaction with obvious bus locking effects). If the SDA line is
observed to be low during initialisation, we automatically attempt to
deblock.

When enabling/disabling a clock or reset signal, confirm that the change
has completed before returning from the function. A somewhat arbitrary
100ms timeout is defined to ensure that the system doesn't lock up in
the case of an error.
Since we need to dynamically determine if we're waiting for a 0 bit or a
1 bit, it's easier to use wait_for_bit_32() than readl_poll_timeout().
This change is needed for reliable initialization of the I2C driver
which is added in a following patch.

Additional testing of the changes introduced in commit 33e06dcbe5 "common:
usb-hub: Reset hub port before scanning") revealed that some USB 2.0 and 3.0
flash drives didn't work in U-Boot on some Allwinner SoCs that support USB
2.0 interfaces only. More precisely, some of the tested USB 2.0 and 3.0
flash drives failed to be detected and work on an OrangePi Zero 3, based on
the Allwinner H616 SoC that supports USB 2.0 only, while the same USB flash
drives worked just fine on a Pine64 H64, based on the Allwinner H6 SoC that
supports both USB 2.0 and USB 3.0 interfaces.
The USB ID of the above-mentioned USB 3.0 flash drive that failed to work is
1f75:0917 (Innostor Technology Corporation IS917 Mass storage), it is 32 GB
in size and sold under the PNY brand. The mentioned USB 2.0 drive is some
inexpensive no-name drive with an invalid USB ID.
Resetting USB 3.0 hubs only, which this patch introduces to the USB hub
resets, has been tested to work as expected, resolving the identified issues
on the Allwinner H616, while not introducing any new issues on other tested
Allwinner SoCs. Thus, let's fix it that way.
According to the USB 3.0 specification, resetting a USB 3.0 port is required
when an attached USB device transitions between different states, such as
when it resumes from suspend. Though, the Linux kernel performs additional
USB 3.0 port resets upon initial USB device attachment, as visible in commit
07194ab7be63 ("USB: Reset USB 3.0 devices on (re)discovery") in the kernel
source, to ensure proper state of the USB 3.0 hub port and proper USB mode
negotiation during the initial USB device attachment and enumeration.
These additional types of USB port resets don't exist for USB 2.0 hubs,
according the USB 2.0 specification. The resets seem to be added to the USB
3.0 specification as part of the port and device mode negotiation.
The Linux kernel resets USB 3.0 (i.e. SuperSpeed) hubs only, as visible in
commit 10d674a82e55 ("USB: When hot reset for USB3 fails, try warm reset.")
in the kernel source. The check for SuperSpeed hubs is performed in a way
that also applies to newer SuperSpeed Plus (USB 3.1 or 3.2) hubs as well,
which hopefully makes it future proof.
