main/i2c: use var block mode for UPTIME_SECS and TMR_ERROR_CNT 

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.

Block registers contain in the first byte the size of data that follows.
This also applies to the registers with the fixed size like UPTIME_SECS_.

Get the uptime of the MoniMod (in seconds).
The fist byte of the register contains the number of bytes of data.
For this register, its value is fixed to 4.

When software mitigation through COAST is enabled (see
:ref:`coast_sec`), one can access the TMR_ERROR_CNT counter using
this command. Setting `TMR Error` bit in STATUS_CML_ clears the value of this
register.
The fist byte of the register contains the number of bytes of data.
For this register, its value is fixed to 4.
