The names of rtc_wake_setup() and cmos_wake_setup() don't indicate
that these functions are ACPI-related, which is the case, and the
former doesn't really reflect the role of the function.
Rename them to acpi_rtc_event_setup() and acpi_cmos_wake_setup(),
respectively, to address this shortcoming.

Notice that cmos_wake_setup() is the only user of acpi_rtc_info and it
can operate on the cmos_rtc variable directly, so it need not set the
platform_data pointer before cmos_do_probe() is called. Instead, it
can be called by cmos_do_probe() in the case when the platform_data
pointer is not set to implement the default behavior (which is to use
the FADT information as long as ACPI support is enabled).
Modify the code accordingly.
While at it, drop a comment that doesn't really match the code it is
supposed to be describing.

RTC chips on some older Chromebooks can only handle alarms less than 24
hours in the future. Attempts to set an alarm beyond that range fails.
The most severe impact of this limitation is that suspend requests fail
if alarmtimer_suspend() tries to set an alarm for more than 24 hours
in the future.
Try to set the real-time alarm to just below 24 hours if setting it to
a larger value fails to work around the problem. While not perfect, it
is better than just failing the call. A similar workaround is already
implemented in the rtc-tps6586x driver.
Drop error messages in cros_ec_rtc_get() and cros_ec_rtc_set() since the
calling code also logs an error and to avoid spurious error messages if
setting the alarm ultimately succeeds.

The additional macro needed were added to dwb ip specific header file
(dcnxx_dwb.h) instead of soc resource file (dcnxx_resource.c). Due to
this pattern, BASE macro had to be redefined in dcnxx_dwb.h, which in
turn needed us to undefine them in the resource file.
[How]
Add a separate macro for DWB access to the resource files that need it
instead of defining them in DWB ip header file. This will enable us to
reuse the BASE macro defined in the resource file.
