drivers: replace packed attributes

MSVC struct packing is not compatible with GCC. Replace macro
__rte_packed with __rte_packed_begin to push existing pack value
and set packing to 1-byte and macro __rte_packed_end to restore
the pack value prior to the push.

Macro __rte_packed_end is deliberately utilized to trigger a
MSVC compiler warning if no existing packing has been pushed allowing
easy identification of locations where the __rte_packed_begin is
missing.

drivers: move alignment attribute on types for MSVC

Move location of __rte_aligned(a) to new conventional location. The new
placement between {struct,union} and the tag allows the desired
alignment to be imparted on the type regardless of the toolchain being
used for both C and C++. Additionally, it avoids confusion by Doxygen
when generating documentation.

event/octeontx: validate events requested against available

Validate events configured in ssopf against the total number of
events configured across all the RX/TIM event adapters.

Events available to ssopf can be reconfigured by passing the required
amount to kernel bootargs and are only limited by DRAM size.
Example:
ssopf.max_events= 2097152
