drm/i915/bios: Fix ports mask

PORT_A to PORT_F are regular integers defined in the enum port,
while for_each_port_masked requires a bit mask for the ports.

Current given mask: 0b111
Desired mask: 0b111111

I noticed this while Christoph was reporting a bug found on headless
GVT configuration which bisect blamed commit 3ae04c0 ("drm/i915/bios:
limit default outputs to ports A through F")

v2: Avoid unnecessary line continuations as pointed by CI and Christoph
