firmware/sysfb: Fix VESA format selection
Some legacy BIOSes report no reserved bits in their 32-bit rgb mode,
breaking the calculation of bits_per_pixel in commit f35cd3fa7729
("firmware/sysfb: Fix EFI/VESA format selection"). However they report
lfb_depth correctly for those modes. Keep the computation but
set bits_per_pixel to lfb_depth if the latter is larger.
v2 fixes the warnings from a max3() macro with arguments of different
types; split the bits_per_pixel assignment to avoid uglyfing the code
with too many typecasts.
v3 fixes space and formatting blips pointed out by Javier, and change
the bit_per_pixel assignment back to a single statement using two casts.
v4 go back to v2 and use max_t()
