Alan Jian 5865d99fe8 hw/display/bcm2835_fb: Fix framebuffer allocation address
This patch fixes the dedicated framebuffer mailbox interface by
removing an unneeded offset.  This means that we pick the framebuffer
address in the same way that we do if the guest code uses the buffer
allocate mechanism of the bcm2835_property interface (case
0x00040001: /* Allocate buffer */ in bcm2835_property.c).

The documentation of this mailbox interface doesn't say anything
about using parts of the request buffer address to affect the
chosen framebuffer address:
https://github.com/raspberrypi/firmware/wiki/Mailbox-framebuffer-interface

Some baremetal applications like the Screen01/Screen02 examples from
Baking Pi tutorial[1] didn't work before this patch.
