Add a new structure, ice_nvm_access, used to request access to read or
write certain NVM related registers.
The structure is used by NVM Update to request read or write of specific
NVM registers in order to perform updates.
Additionally, there is a command to request the driver "features"
structure which represents data about what features of the NVM access
interface the driver supports.
Implement ice_handle_nvm_access to parse the access request and perform
the necessary function.
This function verifies that the access request is valid. If so, the
function will delegate to perform the register read, register write, or
copying of the driver ice_nvm_features structure.
If the request is invalid, the function will report a suitable error
codition that can be propagated out.
Only a subset of registers is accessible, and all other registers will
be rejected with ICE_ERR_OUT_OF_RANGE.
When reading, the contents of the variable sized data buffer will be
used as storage for returning the register value. When writing, the
contents will be used as input for the value to write to the register.

entry. The usual flow in XLT management would iterate through all
characteristics of the input VSI and create a new VSIG and TCAMs till a
matching characteristic is found. When a match is found the VSI is moved
into a matching VSIG and entries are collapsed, leading to added package
update calls. This function serves as an optimization if we know
beforehand that the input VSI has characteristics same as VSI configured
previously added to a VSIG. This is particularly useful for VF VSIs
which are all usually programmed with the same configurations.

The GLV_REPC register contains statistics for tracking received packets
that are discarded due to certain errors.
This register behaves differently from some of the other related
statistics registers in two ways. First, it contains two 16bit
statistics, and thus cannot be read as a 32bit or 40bit statistic.
Second, the two stats do not roll over, but instead cap at 0xFFFF.
Add a new ice_stat_update_repc function which will read the register and
increment the appropriate statistics in the ice_eth_stats structure.
Since the register does not roll over, make use of the "Write Clear"
behavior, and write to the register to reset it every time we read it.
Add extra space for the two statistics that are counted by this
register, rx_errors, and rx_no_desc.
For now, wrap the new function and stats counters in !LINUX_SUPPORT.
This can later be removed if and when the Linux driver implements
support for reading the statistics.
