In order for the user to flush PCIE he needs to read some register
from PCIE block. The chosen register is SPECIAL_GLBL_SPARE_0 and
hence needs to be unsecured.

Up until now the module iterator called void callback functions
and so caller activating callback that may fail suffered from 2 issues:
1. The need to "plant" return called in the private data. This is a
drawback since the iterator itself should not be aware of the private
data of the caller.
2. Due to 1 even in a failure the iterator would keep iterating instead
of break upon error.
To overcome this an optional rc field added to the iterator context.

Following patches are going to add more reserved sync objects and
monitors.
To make the counting of these reserved resources simpler, replace the
existing RESERVED_* defines with enumerations.

Use the generic security module to block all registers in the ASIC and
then open only those that are needed to be accessed by the user.
