Fix unnecessary or unbalanced braces.

Alignment should always match open parenthesis.
Also remove two unnecessary blank lines

Use the BIT macro were possbiel.

u32 should be used instead of uint32_t

Use sizeof where possible to ensure we don't read/write more than the
allocated buffer.

ds1307->regs is never used before being read or initialized locally. There
is no point in keeping a copy in memory.

Also limit the size of the read buffer to what is really used, rename buf
to regs for consistency and use sizeof() where possible.

Based on QNAP's arch/arm/mach-rtk119x/driver/rtk_rtc_drv.c code and
mach-rtk119x/driver/dc2vo/fpga/include/mis_reg.h register definitions.

The base year 2014 was observed on all of Zidoo X9S, ProBox2 Ava and
Beelink Lake I.
