[PULL 49/68] Revert "hw/i386/pc: Confine system flash handling to pc_sysfw"

[Michael S. Tsirkin]

From: Bernhard Beschow <shentey@gmail.com>

Specifying the property `-M pflash0` results in a regression:
  qemu-system-x86_64: Property 'pc-q35-9.0-machine.pflash0' not found
Revert the change for now until a solution is found.

This reverts commit 6f6ad2b24582593d8feb00434ce2396840666227.
