[PATCH] PCI: designware-ep: Fix the Header Type check

[Zhiqiang Hou]

From: Hou Zhiqiang <zhiqiang....@nxp.com>

The current check will result in the multiple function device
fails to initialize. So fix the check by masking out the
multiple function bit.

Fixes: 0b24134f7888 ("PCI: dwc: Add validation that PCIe core is set to correct 
mode")
