[ Upstream commit 0f673c16c850250db386537a422c11d248fb123c ]
Some products (So) may have two different types of products
with different mac-type that are otherwise equivalent, and
have the same PNVM data, so the PNVM file will contain two
(or perhaps later more) HW-type TLVs. Accept the file and
use the data section that contains any matching entry.

[ Upstream commit ff11a8ee2d2d0f78514ac9b42fb50c525ca695c7 ]
If the SKU_ID doesn't match, we don't increment the pointer and keep
checking the same TLV over and over again.
We need to increment the pointer in all situtations, namely if the TLV
is not a SKU_ID, if the SKU_ID matched or if the SKU_ID didn't match.
So we can increment the pointer already before checking for these
conditions to solve the problem.

[ Upstream commit 4a81598f0f39cffbf1c29c4a184063d513661c4a ]
When the interface goes up, we have already loaded the PNVM during
init, so we don't load it anymore. But we still need to set the PNVM
values in the context so that the FW can load it again.
Call set_pnvm when the PNVM is already loaded and change the
trans_pcie implementation to accept a second call to set_pnvm when we
have already allocated and, in this case, only set the values without
allocating again.

[ Upstream commit 82a08d0cd7b503be426fb856a0fb73c9c976aae1 ]
If loading the PNVM file failed on the first try during the
interface up, the file is unlikely to show up later, and we
already don't try to reload it if it changes, so just don't
try loading it again and again.
This also fixes some issues where we may try to load it at
resume time, which may not be possible yet.

[ Upstream commit 1c58bed4b7f7551239b9005ad0a9a6566a3d9fbe ]
Even if we don't reload the file from disk, we still need to
trigger the PNVM load flow with the device; fix that.

The driver looks for a PNVM file that contains FW configuration data
for each different HW combination. The FW requests the data for a
certain SKU_ID and the driver tries to find it in the PNVM file.
Read the file, parse its contents and send it to the trans.

The PNVM code is generic and can be used by other opmodes. Move it to
a common file and include it in the relevant opmodes.
