Unify on using poll_timeout_us() throughout instead of mixing with
readx_poll_timeout(). While the latter can be ever so slightly simpler,
they are both complicated enough that it's better to unify on one
approach only.
While at it, better separate the handling of error returns from
drm_dp_dpcd_readb() and the actual status byte. This is best achieved by
inlining the read_fec_detected_status() function, and switching to
drm_dp_dpcd_read_byte().

Prefer generic poll helpers over i915 custom helpers.
The "two tier" wait_for_us() + wait_for() combination appeared without
much explanation in commit 4e6c2d58ba ("drm/i915: Take forcewake once
for the entire GMBUS transaction"). Try to mimic roughly the same with
the generic helpers.
wait_for_us() with 10 us or shorter timeouts ends up in
_wait_for_atomic(). Thus use poll_timeout_us_atomic() for the first try,
with the same 2 us timeout and no sleep.
For the fallback, the functional change is losing the exponentially
growing sleep of wait_for(), which used to be 10, 20, 40, ..., 640, and
1280 us. Use an arbitrary constant 500 us sleep instead. The timeout

Use REG_BIT() instead of open coding the shift in the FW_BLC_SELF_*
macro definitions to avoid potentially typing them as 'int'.
For example, this happens when we pass them to _MASKED_BIT_ENABLE(),
because of the typeof() construct there. When we pass 1 << 15 (the
FW_BLC_SELF_EN macro), we get typeof(1 << 15), which is 'int'. Then
the value becomes negative (-2147450880) and we try to assign it to a
'u32'.
In practice this is not a problem though, because when we try to
assign -2147450880 to the u32, that becomes 0x80008000, which was the
intended result.

Currently, when adding the 6 GHz Band Capabilities element, the channel
list of the wiphy is checked to determine if 6 GHz is supported for a given
virtual interface. However, in a multi-radio wiphy (e.g., one that has
both lower bands and 6 GHz combined), the wiphy advertises support for
all bands. As a result, the 6 GHz Band Capabilities element is incorrectly
included in mesh beacon and station's association request frames of
interfaces operating in lower bands, without verifying whether the
interface is actually operating in a 6 GHz channel.
Fix this by verifying if the interface operates on 6 GHz channel
before adding the element. Note that this check cannot be placed
directly in ieee80211_put_he_6ghz_cap() as the same function is used to
add probe request elements while initiating scan in which case the
interface may not be operating in any band's channel.
