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

Browse Source 
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Yes, I read that this file is obsolete, but it still has some useful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
# moving from 4.7-git1 to 4.8-rc2-git3
$ cd ~/linux-4.7-git1 # change to the kernel source dir
$ patch -p1 -R < ../patch-4.7-git1 # revert the 4.7-git1 patch
# we now have a 4.7 kernel
$ patch -p1 < ../patch-4.8-rc2 # apply the 4.8-rc2 patch
# the kernel is now 4.8-rc2
$ patch -p1 < ../patch-4.8-rc2-git3 # apply the 4.8-rc2-git3 patch
# the kernel is now 4.8-rc2-git3
$ cd ..
