[PATCH 1/1] trace: conserve gd register on RISC-V

Heinrich Schuchardt
An UEFI application may change the value of the register that gd lives in.
But some of our functions like get_ticks() access this register. So we
have to set the gd register to the U-Boot value when entering a trace
point and set it back to the application value when exiting the trace
point.
