* [PATCH 1/3] scripts: remove unnecessary ihex2fw and check-lc_ctypes from .gitignore

Commit c512d2544c68 ("gitignore: ignore scripts/ihex2fw") was unneeded
because ihex2fw was generated in firmware/ instead of scripts/ at
that time. I guess it was accidentally added because ihex2fw.c was
pushed back and forth between those two directories according to
8b249b6856f1 ("fix modules_install via NFS") and 556b0f58bbcd (Revert
"fix modules_install via NFS"). Of course, you may cross file-moves
during git-bisect, but we do not generally add removed binaries to
the .gitignore file.

check-lc_ctype was removed by commit cb43fb5775df ("docs: remove
DocBook from the building system").

Commit df85b2d767aa ("firmware: Restore support for built-in firmware")
should not have restored this .gitignore blindly.

What git should ignore is merely *.gen.S now.

Clean up the Makefile. Equivalent *.gen.S files are produced.

 - Use filechk to remove ugly wordsize_deps

 - Get FWNAME, FWSTR, ASM_WORD, ASM_ALIGN, and PROGBITS out of the
   recipe for readability

 - Move mkdir into the recipe

 - Clean up generated directories by 'make clean'

For this patch to work correctly,
the following prerequisite is necessary:

https://patchwork.kernel.org/patch/10707461/

So, I will queue this series to kbuild tree.

BTW, my next plan is to move firmware/ to
more relevant place, for example,
drivers/base/firmware_loader/builtin.

This 'find' emits a warning for out-of-tree build.
So, I will get it back to the original code.

Removed this line because filechk creates the directory automatically.

Then, applied to linux-kbuild.
