cxl/acpi: Fix setup of memory resource in cxl_acpi_set_cache_size()

In order to compare the resource against the HMAT memory target,
the resource needs to be memory type. Change the DEFINE_RES()
macro to DEFINE_RES_MEM() in order to set the correct resource type.
hmat_get_extended_linear_cache_size() uses resource_contains()
internally. This causes a regression for platforms with the
extended linear cache enabled as the comparison always fails and the
cache size is not set. User visible impact is that when 'cxl list' is
issued, a CXL region with extended linear cache support will only
report half the size of the actual size. And this also breaks MCE
reporting of the memory region due to incorrect offset calculation
for the memory.
