YRabbit 2e8280a949 Gowin. Fix pipeline mode in BSRAM.
It seems that the internal registers on the BSRAM output pins in
READ_MODE=1'b1 (pipeline) mode do not function properly because in the
images generated by Gowin IDE an external register is added to each pin,
and the BSRAM itself switches to READ_MODE=1'b0 (bypass) mode .

This is observed on Tangnano9k and Tangnano20k boards.

Here we repeat this fix.
