[PATCH 1/2] xen/Kconfig: define EXPERT a bool rather than a string

[Julien Grall <julien@xxxxxxx>]

From: Julien Grall <jgrall@xxxxxxxxxx>

Since commit f80fe2b34f08 "xen: Update Kconfig to Linux v5.4" EXPERT
can only have two values (enabled or disabled). So switch from a string
to a bool.

Take the opportunity to replace all "EXPERT = y" to "EXPERT".
