periph/i2c: convert char to uint8_t where applicapable
...
In general, data transferred through I2C are bytes and thus should have
type uint8_t, not char.
Also convert uint8_t ptrs to void ptrs

cpu: removed NAKED attribute from ISRs
...
- removed the __attribute__((naked)) from ISRs
- removed ISR_ENTER() and ISR_EXIT() macros
Rationale: Cortex-Mx MCUs save registers R0-R4 automatically
on calling ISRs. The naked attribute tells the compiler not
to save any other registers. This is fine, as long as the
code in the ISR is not nested. If nested, it will use also
R4 and R5, which will then lead to currupted registers on
exit of the ISR. Removing the naked will fix this.
