thermal/drivers/mediatek/lvts_thermal: Fix wrong lvts_ctrl index

In 'lvts_should_update_thresh()' and 'lvts_ctrl_start()' functions,
the parameter passed to 'lvts_for_each_valid_sensor()' macro is always
'lvts_ctrl->lvts_data->lvts_ctrl'. In other words, the array index 0
is systematically passed as 'struct lvts_ctrl_data' type item, even
when another item should be consumed instead.

Hence, the 'valid_sensor_mask' value which is selected can be wrong
because unrelated to the 'struct lvts_ctrl_data' type item that should
be used. Hence, some thermal zone can be registered for a sensor 'i'
that does not actually exist. Because of the invalid address used
as 'lvts_sensor[i].msr', this situation ends up with a crash in
'lvts_get_temp()' function, where this 'msr' pointer is passed to
'readl_poll_timeout()' function. The following message is output:
"Unable to handle kernel NULL pointer dereference at virtual
address <msr>", with <msr> = 0.

This patch fixes the issue.

Merge tag 'thermal-v6.10-rc1' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/thermal/linux into thermal

Merge updates of thermal drivers for v6.10 from Daniel Lezcano:

"- Add QCM2290 compatible DT bindings for Lmh and fix a null pointer
dereference in the lmh driver in case the SCM is not present (Konrad
Dybcio)

- Use the strreplace() function instead of doing it manually in the
Armada driver (Rasmus Villemoes)

- Convert st,stih407-thermal to DT schema and fix up missing
properties (Raphael Gallais-Pou)

- Add suspend/resume by restoring the context of the tsens sensor
(Priyansh Jain)

- Support A1 SoC family Thermal Sensor controller and add the DT
bindings (Dmitry Rokosov)

- Improve the temperature approximation calculation and consolidate
the Tj constant into a shared area of the structure instead of
duplicating it on the Rcar Gen3 (Niklas Söderlund)

- Fix the Mediatek LVTS sensor coefficient for the MT8192 in order to support
it correctly (Hsin-Te Yuan)

- Fix a null pointer dereference on the tsens driver when the function
compute_intercept_slope() is called with a null parameter (Aleksandr
Mishin)

- Remove some unused fields in struct qpnp_tm_chip and k3_bandgap
(Christophe Jaillet)

- Fixup calibration efuse data decoding, consolidate the code by
checking boundaries and refactor some part of the LVTS Mediatek
driver. After setting the scene, add MT8186 and MT8188 along with
the DT bindings (Nicolas Pitre)

- Add Loongson-2K2000 support after some minor code adjustements and
providing the DT bindings definition (Binbin Zhou)"

thermal/drivers/mediatek/lvts_thermal: Allow early empty sensor slots

Some systems don't always populate sensor controller slots starting
at slot 0. Use a bitmap instead of a count to indicate valid sensor
slots. Also create a pretty iterator for that.

About that iterator: it causes checkpatch to complain with "ERROR:
Macros with multiple statements should be enclosed in a do - while
loop". However this is not possible here. And many similar iterators
do exist using the same form in the tree already.
