Improve performance and readability of rtc_read_time() by reading only the 7 time registers, instead of reading 8 registers (additional CTRL3 register). We drop reading of CTRL3 to monitor the low battery flag, as this check is already available in the ioctl. Anyway, this check only display an info message and has no other impacts. The code readability also improves as we do not have to fiddle with buffer pointer and size arithmetic.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
