Thanks to this change the linux kernel may use PEC for these registers
in much easier way.

In pytest, update query flags for TEMP_CURVE_POINTS and TEMP_MATRIX_ROW
registers.

Changes cover:
- fix broken handling of setting row/points (size of temp_matrix_row was too
  small, fan_n in set_tc_curve was read from a wrong type (uint16 not uint8))
- use structures for handling row/points
- add get functionality for row/points (before it was possible to read only
  the transfered data not the actual used)
- iterate over fan entries when getting row/points
- update pytests
  -- update query flags for TEMP_CURVE_POINTS and TEMP_MATRIX_ROW registers
  -- improve write testing of TEMP_CURVE_POINTS and TEMP_MATRIX_ROW
     registers
- update documentation

The line:
*cmds->cmds[cmd_index].data_len = tx_tmp;
triggered the write to memory, which is declared as read-only (const).
Such writes trigger the memory exception.

To make the code simpler and avoid problematic write,
support only writes that has a size of a register.

The fix was tested for PEC.

Without PEC the i2c write transaction is finished before the execution of a callback.
Make the same behavior when the PEC is used.
Triggering a reset over i2c returns write failure if the transaction is not finished.
