gpu: nvgpu: gv11b: init and implement reset_enable_hw
-implement gv11b specific reset_enable_hw fifo ops
-timeout period in fifo_fb_timeout_r() is set to init instead of max
This register specifies the number of microseconds Host
should wait for a response from FB before initiating a timeout interrupt.
For bringup, this value should be set to a lower value than usual, such as
~.5 milliseconds (500), to help find out bugs in the memory subsystem.
-timeout period in pbdma_timeout_r() is set to init instead of max
This register contains a value used for detecting timeouts.
The timeout value is in microsecond ticks.
The timeouts that use this value are:
GPfifo fetch timeouts to FB for acks, reqs, rdats.
PBDMA connection to LB.
GPfifo processor timeouts to FB for acks, reqs, rdats.
Method processor timeouts to FB for acks, reqs, rdats.
The init value is changed to 64K us based on bug 1816557.
