Rename R-Mobile to Renesas all over the place because the chips are
made by Renesas, while only a subset of them is from the R-Mobile line.

Rename ARCH_RMOBILE to ARCH_RENESAS because all the chips are made
by Renesas, while only a subset of them is from the R-Mobile
line.

Use the following command to perform the rename:

"
$ git grep -l 'ARCH_RMOBILE' | xargs -I {} sed -i 's@ARCH_RMOBILE@ARCH_RENESAS@g' {}
"

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.

Device tree improvents for Paz00 and DM PMIC convertion of recently
merged Tegra boards.

The "i2cbcdev" sneaked in when implementing this function for the
bootcounter use case. Obviously the intention was to use prop_name
instead.

Now that we have time conversion defines from in time.h there is no need
for each driver to define their own version.

This new function enhances the i2c_get_chip*() toolbox by implementing a
variant that does not require a chip_addr. Instead, the desired device
is pointed to by a phandle.

In SPL probing of the designware_i2c device on the StarFive VisionFive 2
board fails with

    dw_i2c: mode 0, ic_clk 1000000, speed 100000,

When changing the offset for the high phase from 7 to 3 the device is
probed correctly. This now matches the value from the Linux driver.

Without this fix the memory size of the StarFive VisionFive 2 board cannot
be read from EEPROM.
