mini-os: add map_frame_virt() function

Add a function map_frame_virt() to map a given frame and return its
virtual address.

On arm we just use the frame physical address, while on x86 we take a
page from the virtual kernel area. For this purpose make this area
available even in case of undefined CONFIG_BALLOON.
