tcl/interface: universal config for all Raspberry Pi models

Speed calibration coeffs are computed from cpufreq/scaling_max_freq
and from the device-tree compatibility information.

Raspberry Pi linux offers /dev/gpiomem for non-root access
to the GPIO registers since ~2016.
Do not configure 'bcm2835gpio peripheral_base' as it is necessary
only if /dev/mem is used - it requires running OpenOCD as root
- it's a security risk so it should be avoided.

The configuration of the GPIO connector (40-pin header)
is factored out and ready to use in interface configuration
for other driver (e.g. linux gpiod).

Mark raspberrypi2-native.cfg as deprecated and redirect
it to raspberrypi-native.cfg
