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.

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.

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.

HackRF One: add resistance to amplifier supplies

This may improve reliability since switching to a MOSFET with lower on
resistance.
