Nick Huang 73c4638a28 rtc: s35390a: use u8 instead of char for register buffer
The register buffer in s35390a_get_reg() was previously defined as
`char *buf`. This is not ideal since register data represents raw
binary values rather than textual data.

Switch the type to `u8 *buf` to better reflect its intended usage and
to avoid potential issues with sign extension when handling register
values on platforms where `char` is signed by default.

This change improves type safety and makes the code consistent with
other RTC drivers that operate on raw register data.
