habanalabs/gaudi2: increase hard-reset sleep time to 2 sec
The access to the device registers is blocked during hard reset, until
preboot runs and allows the access to specific registers, including the
PSOC BTM_FSM register which is used to know when the reset is done.
Between the reset request and until this register is polled there is a
small delay of 500 msec which is not enough for F/W to process the reset
and for preboot to run, so the register might be accessed while it is
blocked.
To avoid it, increase the delay to 2 sec.
