Subject: [PATCH v2] xen: x86: remove setting the obsolete config XEN_MAX_DOMAIN_MEMORY

Commit c70727a5bc18 ("xen: allow more than 512 GB of RAM for 64 bit
pv-domains") from July 2015 replaces the config XEN_MAX_DOMAIN_MEMORY with
a new config XEN_512GB, but misses to adjust arch/x86/configs/xen.config.
As XEN_512GB defaults to yes, there is no need to explicitly set any config
in xen.config.

Just remove setting the obsolete config XEN_MAX_DOMAIN_MEMORY.
