Series chardev: implement backend chardev multiplexing | expand

Commit Message

Roman Penyaev Oct. 16, 2024, 10:25 a.m. UTC 
In the following patches backend multiplexer will be
introduced. This patch renames the structure and a
few mux macros to reflect that this mux is responsible
only for multiplexing of frontend devices.

This patch does the following:

  s/MuxChardev/MuxFeChardev/g
  s/CHARDEV_IS_MUX/CHARDEV_IS_MUX_FE/g
  s/MUX_CHARDEV/MUX_FE_CHARDEV/g
  s/TYPE_CHARDEV_MUX/TYPE_CHARDEV_MUX_FE/g

No json or string types are changed for the sake of
compatibility.
