With this patch, we don't have a single target using the 1588 timer support.
This means that it will get broken in the future.

Is this used?

With this patch, the meson configuration is unaligned with the make
configuration.

If I look before the patch:

origin/master:config/meson.build:dpdk_conf.set('RTE_LIBRTE_DPAA2_USE_PHYS_IOVA',
true)
origin/master:config/arm/meson.build:
['RTE_LIBRTE_DPAA2_USE_PHYS_IOVA', false]]

origin/master:config/common_base:CONFIG_RTE_LIBRTE_DPAA2_USE_PHYS_IOVA=y
origin/master:config/defconfig_arm64-dpaa2-linuxapp-gcc:CONFIG_RTE_LIBRTE_DPAA2_USE_PHYS_IOVA=n

And in the history, I understand:
- option (with dpaa2 in the name) introduced and enabled for all
- later, disabled for dpaa2

Does it mean the option can be removed?
