[Qemu-trivial] [PULL 21/22] docs/memory.txt: Fix document on MMIO operations

[Michael Tokarev]

From: Fam Zheng <address@hidden>

.impl.valid should be .impl.unaligned and the description needs some
fixes.

.old_portio is removed since commit b40acf99b (ioport: Switch
dispatching to memory core layer).
