LoongArch: Fix reserving screen info memory for above-4G firmware

Browse Source 
[ Upstream commit 55dc2f8f26 ]

Since screen_info.lfb_base is a __u32 type, an above-4G address need an
ext_lfb_base to present its higher 32bits. In init_screen_info() we can
use __screen_info_lfb_base() to handle this case for reserving screen
info memory.
