Hook ssram init && de-init functions to vdev
devices lifecycle management:
1) initialize ssram when vdev devices
are initialized.
2) de-initialize ssram when vdev devices
are reset or destroyed.
notes:
ssram configuration data can be released only when
user VM shutdown, hence it can't be done in deinit_vssram().
- VM reboot:
do deinit_vssram() only.
- VM shutdown:
do both deinit_vssram() and clean_vssram_config().

According to PCIe specification (since 2.0), absence of any extended
capabilities is required to be indicated by an extended capability header
with a capability ID of FFFFh and a next capability offset of 000h. Thus,
the board inspector today accesses the first extended capability header at
100h in the configuration space of a PCIe function unconditionally.
However, in practice we have seen real PCI functions which has a PCIe
capability but no extended capability header. This will cause the board
inspector to crash due to invalid configuration space accesses.
To fix that, this patch adds a check to the size of the configuration space
before walking the extended capabilities of a PCIe function.
