jtag: drivers: bcm2835gpio: set 4ma drive, slow slew rate
Both the drive strength and slew rate are currently set to very high
values. This causes the waveforms to overshoot and be less reliable
when operating at high speed.
This patch lowers the slew rate and sets the drive strength to 4ma,
improving the waveform output.
