Pali Rohár 049704f808 board_f: Fix types for board_get_usable_ram_top()
Commit 37dc958947 ("global_data.h: Change ram_top type to phys_addr_t")
changed type of ram_top member from ulong to phys_addr_t but did not
changed types in board_get_usable_ram_top() function which returns value
for ram_top.

So change ulong to phys_addr_t type also in board_get_usable_ram_top()
signature and implementations.

Fixes: 37dc958947 ("global_data.h: Change ram_top type to phys_addr_t")
