[PATCH v2 01/19] xen/x86: remove "depends on !PV_SHIM_EXCLUSIVE"

[Penny Zheng <Penny.Zheng@xxxxxxx>]

We intend to remove all "depends on !PV_SHIM_EXCLUSIVE" (also the functionally
equivalent "if !...") in Kconfig file, since negative dependancy will badly
affect allyesconfig.
This commit is based on "x86: provide an inverted Kconfig control for
shim-exclusive mode"[1]
