This was a remnant from porting kernel code to barebox.
While being uncritical so far, this will now cause a compiler error
since kzalloc is not a define but a static inline function.

As the kzalloc() 'mode' argument was ignored before and still will be,
it is safe to remove the parameter.

Instead of using udelay and a countdown, use the is_timeout function.
Also, move the code closer to the kernel version, i.e. check for the
correct bank and clean the interrupt status.

The interrupt mask is incorrect in case of HW error correction.
The driver will time out waiting for the wrong interrupts.

It causes build failures on other arches than socfpga and the driver
doesn't use anything provided by this header.

A read id operation followed by 0x00 reads the device ID while
a read id operation followed by 0x20 reads the possible ONFI identifier.

As the READID function did not propagate the second id parameter but had
a hard-coded call for 0x90 0x00, reading the ONFI identifier was not
possible and thus chips werde not detected (tested with
MT29F8G08ABABAWP)
