The CSR SiRF prima2/atlas platforms are getting removed, so this driver
is no longer needed.

Move the alarm callbacks in pcf85063_rtc_ops and use RTC_FEATURE_ALARM to
signal to the core whether alarms are available instead of having a
supplementary struct rtc_class_ops without alarm callbacks.

Introduce a bitfield to allow the drivers to announce the available
features for an RTC.
The main use case would be to better handle alarms, that could be present
or not or have a minute resolution or may need a correct week day to be set.
Use the newly introduced RTC_FEATURE_ALARM bit to then test whether alarms
are available instead of relying on the presence of ops->set_alarm.

The rtc-s5m uses the I2C regmap but doesn't select it in Kconfig so
depending on the configuration the build may fail. Fix it.

Add compatible for SAMA7G5 RTC. At the moment the driver is falling
back on SAM9X60's compatible but SAMA7G5 doesn't have the tamper mode
register and tamper debounce period register thus the need for a new
compatible to differentiate b/w these two in case tamper feature will
be implemented in future.

Since commit 36e2c7421f02 ("fs: don't allow splice read/write without
explicit ops") we've required that file operation structures explicitly
enable splice support, rather than falling back to the default handlers.
Most /proc files use the indirect 'struct proc_ops' to describe their
file operations, and were fixed up to support splice earlier in commits
40be821d627c..b24c30c67863, but the mountinfo files interact with the
VFS directly using their own 'struct file_operations' and got missed as
a result.
This adds the necessary support for splice to work for /proc/*/mountinfo
and friends.
