From: Pavan Nikhilesh <pbhagavatula at marvell.com>
MSI-X permits a device to allocate up to 2048 interrupts as per PCIe
spec.
Increase the max number of vectors to a reasonable value of 512.

v3 Changes:
- Instead of making it a configurable option set max vectors to a reasonable
value of 512.
v2 Changes:
- Add defaults for meson build. (Jerin Jacob)
