docs: Stipulate that block size must be >= 4K and a power-of-2

Arguments and responses to most commands are given in block size which
is decided on during the version negotiation process when GET_MBOX_INFO
is called.

We require that block size is greater than 4K (12 bit). The lpc bus
address space is 28 bit and commands which return an lpc bus address have
a 16 bit variable space, this means we can correctly specify anywhere in
the lpc address space.

This also allows us to support flash sizes up to 256MB where we can
correctly specify any flash offset in the command arguments.
