[PATCH v4 9/9] target/i386/tcg/sysemu/tcg-cpu: Avoid own opinion about smram size

[Bernhard Beschow <shentey@gmail.com>]

When setting up the CPU's smram memory region alias, the code currently
assumes that the smram size is 4 GiB. While this is true, it repeats a
decision made elsewhere which seems redundant and prone to
inconsistencies. Avoid this by reusing whatever size the smram region
was set to.
