[PATCH V14 05/17] pc_memory_init: Move memory calculation to the caller.
From: Anthony PERARD <anthony.perard@citrix.com>

This patch moves above_4g_mem_size and below_4g_mem_size calculation in
the caller of pc_memory_init (pc_init1). And the prototype of
pc_memory_init is changed because there is no need anymore to have
variable pointer and the ram_size parameter.
