ae2a983f51 HackRF One: change R60 from 0 ohms to 100 ohms 
This matches R31 and was intended to be done when R31 was changed to 100
ohms.

3a20745a6d HackRF One: populate R83 instead of R84 
This removes clock buffer chaining which was intended to be done when
the RC delay was added.

d352952f96 HackRF One: adjust clock phase with RC delay 
Remove chaining of buffers to delay GCK2 and instead use an RC delay for
both GCK2 and SGPIO_CLK.

a4a007ed75 HackRF One: AC couple CLKIN 
We've always specified that CLKIN should be DC (based on the Si5351C
documentation), but it has worked with AC input.  AC coupling the buffer
input restores this undocumented feature.

2154b4227a HackRF One: add resistance to amplifier supplies 
This may improve reliability since switching to a MOSFET with lower on
resistance.

e15bb0e972 HackRF One: chain SGPIO_CLK and GCK2 buffers 
This more closely emulates the clock phase relationships on prior
hardware revisions that used the Si5351C.

Update clock trace widths.

9d71e91e74 HackRF One: change CLKIN_DETECT pin 
- move CLKIN_DETECT to U23 pin 15, P4_8, CTIN_5
- move SGPIO13 to U23 pin 91, P2_5, GPIO5[5]
- rename SGPIO13 to TRIGGER_EN

This allows TIMER1/TIMER2 instead of TIMER3/TIMER0 to be used for CLKIN
detection, avoiding conflicts with PortaPack firmware.

SGPIO13 was never used for SGPIO, so it is renamed to reflect current
usage.

155a4532f0 HackRF One: swap pins for platform detection 
- move EN_1V8 to P5_0, U23 pin 37
- move !VAA_ENABLE to P6_10, U23 pin 100
- move !RX_AMP_PWR back to P2_12, U23 pin 106

Platform detection is now performed using P5_0 and P6_10 which avoids
the complication of having to detect a pull-up to VAA which may not yet
be switched on.

fe42edf790 HackRF One: update hardware detection pin straps 
Additionally swap:
 - EN_1V8, P6_10, U23 pin 100 (pull-down)
 - !RX_AMP_PWR, P2_12, U23 pin 106 (pull-up)

Detecting which has the pull-up and which has the pull-down enables
version detection that may be more reliable than the ADC method.
