72a96a77f8 Call a sample rate a sample rate 
Previously we used "sample rate" to mean a rate that is twice the sample
rate in several places in firmware.

1ad8adb449 Automatically configure Praline baseband LPF 
For compatibility with old host software, the analog baseband filter is
automatically selected based on the sample rate and offset tuning
configuration. The bandwidth set by legacy vendor request is ignored.

6f862a1349 Add pin_shutdown() 
Portions of pin_setup() that establish a safe, low-power state are moved
into the new pin_shutdown(). Use pin_shutdown() to prepare for sleep or
reset or prior to calling pin_setup().

cde5d754d3 Remove 32 kHz oscillator self-test 
Reliable oscillator start-up requires several hundred milliseconds which
is longer than we are willing to wait at every boot. We could add an
on-demand test in the future instead of an automatic self-test.

c19f85ef24 h1r9: use single SSP configuration for MAX283x 
During r9 hardware development it was thought that the MAX2839 would use
a different GPIO pin for chip select, but it ended up being the same pin
as is used for MAX2837 on other hardware revisions.

This takes the MAX283x abstraction a bit further and fixes a bug with
hackrf_debug -m.

273e6a1217 Add an accurate delay loop. 
The existing 'delay' function is not calibrated to any specific measure
of time. Add a new function using a loop with a known cycle count, to
produce delays of a given duration at a given CPU clock speed.

46fd11af5b Si5351C: Extract best block source function into hackrf_core. 
It's not an Si5351C driver thing, but a HackRF thing. Also added a driver function to check if CLKIN signal is valid, and made use of it, instead of opaque register read code.
