Member screen_base in struct fb_info is declared __iomem causing
a sparse warning as below when passed to vfree(). Instead use non-
__iomem pointer screen_buffer to avoid the warning.
fbtft-core.c:922:39: warning: incorrect type in argument 1 \
(different address spaces)
fbtft-core.c:922:39: expected void const *addr
fbtft-core.c:922:39: got char [noderef] <asn:2>*screen_base
