[PATCH v3] Kconfig: fix typos in core makefiles/code and purge remaining ghosts (v3)

[Breno Rodrigues Alves <breno3011alves@gmail.com>]

Analysis from Sashiko AI revealed that several legacy options were not
true dead weight, but rather victims of pre-existing copy-paste typos
in Makefiles and C code.

This patch:
  - Fixes MediaTek interconnect typo mapping mt8196.o to MT8195.
  - Fixes MediaTek regulator typo mapping mt6316-regulator to MT6315.
  - Fixes missing CONFIG_ prefix on DVB_ULE_DEBUG macro in dvb_net.c.
  - Retains critical PCI_IMX6_EP and Tegra audio prompts to keep hidden
    symbols selectable.
  - Cleans up the dangling comment in drivers/leds/Kconfig.
  - Purges the remaining verified ghost weight.

-Some LCDs allow you to define up to 8 characters, mapped to ASCII
-characters 0 to 7. The escape code to define a new character is
-'\e[LG' followed by one digit from 0 to 7, representing the character
-number, and up to 8 couples of hex digits terminated by a semi-colon
-(';'). Each couple of digits represents a line, with 1-bits for each
-illuminated pixel with LSB on the right. Lines are numbered from the
-top of the character to the bottom. On a 5x7 matrix, only the 5 lower
-bits of the 7 first bytes are used for each character. If the string
-is incomplete, only complete lines will be redefined. Here are some
-examples::
-
-  printf "\e[LG0010101050D1F0C04;"  => 0 = [enter]
-  printf "\e[LG1040E1F0000000000;"  => 1 = [up]
-  printf "\e[LG2000000001F0E0400;"  => 2 = [down]
-  printf "\e[LG3040E1F001F0E0400;"  => 3 = [up-down]
-  printf "\e[LG40002060E1E0E0602;"  => 4 = [left]
-  printf "\e[LG500080C0E0F0E0C08;"  => 5 = [right]
-  printf "\e[LG60016051516141400;"  => 6 = "IP"
-
-  printf "\e[LG00103071F1F070301;"  => big speaker
-  printf "\e[LG00002061E1E060200;"  => small speaker
