The get_timer function returns an unsigned long which may be calculated
from the ARM system counter. This counter is reset only on a cold reset.
U-boot divides this counter down to a 1000 Hz counter that will cross
the 32bit barrier after a bit more than 49 days. Assigning the value to
an unsigned int will truncate it on 64bit systems.
Passing this truncated value back to the get_timer function will return
a very large value that is certainly larger than the timeout and so will
go down the error path and besides stopping U-Boot will lead to messages
like
"SPI: QSPI is still busy after poll for 5000 ms."
