Changes for Build #640
[Dan Smith <dsmith at danplanet.com>] Style fix related to patch for #8565

[Jim Unroe <rock.unroe at gmail.com>] [H777] Retevis H777 Plus

Related to #8565

[Jim Unroe <rock.unroe at gmail.com>] [H777] Rework Serial Timeout

The previous patch has broken uploads for the classic BF-888s radios and
newer Retevis H777 models. The constanstant switching of the timeout to .5
before each block is sent and back to .25 after each block is sent on a
Windows computer creates "noise" that causes the apparently "faster"
radios to mis the "ack" returned by the radio which results in the upload
failing.

This patch resolves the issue by setting the serial timeout to .5 and leaving
it remain that way for all serial activity.

fixes #8197

[Jim Unroe <rock.unroe at gmail.com>] [RT22] Remove FRS and PMR446 Frequency Tables

This driver was coded in a way that erasing a memory row would preselect the
appropriate FRS or PMR446 frequency, bandwidth and transmit power level. This
would similar to how the OEM programming software functions (actually the OEM
software has the frequencies, bandwidth and power level settings fixed so that
they cannot be edited).

While getting ready to submit test images for these models, I rediscovered that
the CHIRP test suite regards this as a memory that can't be erased and reports
an error.

This patch removes the frequency tables and other code related to this so that
the test suite will pass when tested with the related "image" files.
