Subject: [PATCH] Hexagon: remove checks for CONFIG_PAGE_SIZE_1MB

There are two checks for CONFIG_PAGE_SIZE_1MB in hexagon's code. But
there is no Kconfig symbol PAGE_SIZE_1MB. Remove these unneeded checks
and the code they hide.

Signed-off-by: Paul Bolle <pebolle@...cali.nl>

Untested.

Richard preferred this over the equally trivial patch to add an entry
for PAGE_SIZE_1MB.
