Subject: drm/i915/tgl: select correct bit for port select

Git-commit: df16b6361d888409a9e2f9ae777c8d5dde2e76b8
Patch-mainline: v5.4-rc1
References: bsc#1152489
Bit definitions for port-select got changed for TRANS_CLK_SEL &
TRANS_DDI_FUNC_CTL registers in TGL.
v2 (Lucas):
- Nuke TRANS_DDI_PORT_NONE since it's 0: we are already clearing
{TGL_,}TRANS_DDI_PORT_MASK (suggested by Ville)
- Also cover haswell_get_ddi_port_state() in intel_display.c that was
missing
- Define macros using the _SHIFT macros so we don't lose other users
