Luis Alberto Herrera e93a977367 mtd: revert "spi-nor: intel: provide a range for poll_timout" 
This change reverts aba3a882a1: "mtd: spi-nor: intel: provide a range
for poll_timout". That change introduces a performance regression when
reading sequentially from flash. Logging calls to intel_spi_read without
this change we get:

Start MTD read
[   20.045527] intel_spi_read(from=1800000, len=400000)
[   20.045527] intel_spi_read(from=1800000, len=400000)
[  282.199274] intel_spi_read(from=1c00000, len=400000)
[  282.199274] intel_spi_read(from=1c00000, len=400000)

[  544.351528] intel_spi_read(from=2000000, len=400000)
End MTD read

With this change:

End MTD read
