Shijith Thotton a986c2b797 build: add option to configure IOVA mode as PA
IOVA mode in DPDK is either PA or VA.
The new build option enable_iova_as_pa configures the mode to PA
at compile time.
By default, this option is enabled.
If the option is disabled, only drivers which support it are enabled.
Supported driver can set the flag pmd_supports_disable_iova_as_pa
in its build file.

mbuf structure holds the physical (PA) and virtual address (VA).
If IOVA as PA is disabled at compile time, PA field (buf_iova)
of mbuf is redundant as it is the same as VA
and is replaced by a dummy field.
