AArch32: Fix detection of virtualization support
The Virtualization field in the ID_PFR1 register has only 2
valid values (0 or 1) but it was incorrectly checked against
unrelated value tied to the SPSR register instead.
This patch fixes the detection of virtualization support by
using the valid values in BL1 context management code.
