xen/arm32: mm: Avoid cleaning the cache for secondary CPUs page-tables

The page-table walker is configured by TCR_EL2 to use the same
shareability and cacheability as the access performed when updating the
page-tables. This means cleaning the cache for secondary CPUs runtime
page-tables is unnecessary.
