docs: process: drop git snapshots from applying-patches.rst

Drop all references to git daily snapshots of Linux mainline git tree
since they are no longer generated.

Drop the "Last update" info since 'git log' is a better source of that
info and since the Last update date is not being updated.

Yes, I read that this file is obsolete, but it still has some useful
information in it.

-The -git kernels
-================
-
-These are daily snapshots of Linus' kernel tree (managed in a git
-repository, hence the name).
-
-These patches are usually released daily and represent the current state of
-Linus's tree. They are more experimental than -rc kernels since they are
-generated automatically without even a cursory glance to see if they are
-sane.
-
--git patches are not incremental and apply either to a base 4.x kernel or
-a base 4.x-rc kernel -- you can see which from their name.
-A patch named 4.7-git1 applies to the 4.7 kernel source and a patch
-named 4.8-rc3-git2 applies to the source of the 4.8-rc3 kernel.

-Here are some examples of how to apply these patches::
-
-	# moving from 4.7 to 4.7-git1

-	$ cd ~/linux-4.7			# change to the kernel source dir
-	$ patch -p1 < ../patch-4.7-git1		# apply the 4.7-git1 patch
-	$ cd ..
-	$ mv linux-4.7 linux-4.7-git1		# rename the kernel source dir
