We have a dedicated pointer for that, so use it. Much easier to read and
less computation involved.

This allows the RX6110 driver to be automatically assigned to the right
device on the I2C bus.

With CONFIG_I2C=m, the #ifdef section is disabled, as shown
by this warning:
drivers/rtc/rtc-rx6110.c:314:12: error: unused function 'rx6110_probe' [-Werror,-Wunused-function]
Change the driver to use IS_ENABLED() instead, which works
for both module and built-in subsystems.

The RX6110 also supports I2C, so this patch adds support for it to the
driver.
This also renames the SPI specific functions and variables to include
`_spi_` in their names.

Add missing <of_device_id> table for SPI driver relying on SPI
device match since compatible is in a DT binding or in a DTS.

The RTC core is always calling rtc_valid_tm after the read_time callback.
It is not necessary to call it just before returning from the callback.

Check for rtc_class_ops structures that are only passed to
devm_rtc_device_register, rtc_device_register,
platform_device_register_data, all of which declare the corresponding
parameter as const. Declare rtc_class_ops structures that have these
properties as const.
The semantic patch that makes this change is as follows:

The RX6110 comes in two different variants: SPI and I2C.
This driver only supports the SPI variant.
If the need ever arises to also support the I2C variant, this driver
could easily be refactored to support both cases.
