[PATCH v4 03/20] xen/x86: remove "depends on !PV_SHIM_EXCLUSIVE"

[Penny Zheng <Penny.Zheng@xxxxxxx>]

Remove all "depends on !PV_SHIM_EXCLUSIVE" (also the functionally
equivalent "if !...") in Kconfig file, since negative dependancy will badly
affect allyesconfig. To make sure unchanging produced config file based
on "pvshim_defconfig", we shall explicitly state according Kconfig is not set

Add "default y" for SHADOW_PAGING and TBOOT, otherwise we will have unset
values when running make defconfig based on "x86_64_defconfig".

Signed-off-by: Penny Zheng <Penny.Zheng@xxxxxxx>
---
v2 -> v3:
- remove comment for PV_SHIM_EXCLUSIVE
---
v3 -> v4:
- explicitly state "CONFIG_xxx is not set" in "pvshim_defconfig"
- Add "default y" for SHADOW_PAGING and TBOOT
- refactor commit message
