I've added a request to remove the RTC references from the DA9063L datasheet.

Adding that first part to the sentence in the commit log: "While the datasheet for DA9063L
(2v1, 23-Mar-2017) lists the RTC register block" is just pointing out an ambiguity from the
datasheet since the it also identifies those registers in Table 102 on page 126 as
"Reserved".

I would like to suggest, the commit log entry: "Add custom IRQ map for DA9063L to ignore
the Alarm and Tick IRQs from the PMIC".

Isn't the number of IRQs in the DA9063L different to the standard DA9063
because of the missing RTC?
