Peter Maydell f8add62c0c hw/display/bcm2835_fb: Validate config settings 
Validate the config settings that the guest tries to set.

The wiki page documentation is not really accurate here:
generally rather than failing requests to set bad parameters,
the hardware will just clip them to something sensible.

Validate the most important parameters: sizes and
the viewport offsets. This prevents the framebuffer
code from trying to read out-of-range memory.

In the property handling code, we validate the new parameters every
time we encounter a tag that sets them. This means we validate the
config multiple times if the request includes multiple config-setting
tags, but the code would require significant restructuring to do a
validation only once but still return the clipped settings for
get-parameter tags and the buffer allocation tag.

Validation of settings made via the older bcm2835_fb_mbox_push()
function will be done in the next commit.
