[PATCH v5] Kconfig: fix typos in core makefiles and purge defective DVB debug (v5)

[PATCH v5] Kconfig: fix typos in core makefiles and purge defective DVB debug (v5)

[Breno Rodrigues Alves]

Automated review from Sashiko AI revealed that re-enabling the legacy
DVB_ULE_DEBUG code via CONFIG_DVB_ULE_DEBUG exposes severe race conditions
on global state variables, leading to out-of-bounds memory corruption.
Additionally, the debug block suffers from undeclared identifiers (TS_SZ).

Following the core kernel principle of eliminating dangerous, unmaintained
code, this patch completely extirpates the defective DVB_ULE_DEBUG block
from dvb_net.c and purges its corresponding configuration symbol from
the Kconfig tree.

This version retains the verified MediaTek bugfixes and ghost purges:
  - Fixes MediaTek interconnect typo mapping mt8196.o to MT8196.
  - Fixes MediaTek regulator typo mapping mt6316-regulator to MT6316.
  - Cleans up the dangling comment in drivers/leds/Kconfig.
  - Purges verified legacy ghost weight.

Generally, the rule is wait a day between resends.  Otherwise it
becomes pair programming and no one wants that.
