acpi, nfit: kill ACPI_NFIT_DEBUG

Browse Source 
Inevitably when one actually needs to debug a DSM issue it's on a
distribution kernel that has CONFIG_ACPI_NFIT_DEBUG=n. The config symbol
was only there to avoid the compile error due to the missing fallback for
print_hex_dump_debug in the CONFIG_DYNAMIC_DEBUG=n case. That was fixed
with commit cdf17449af "hexdump: do not print debug dumps for
!CONFIG_DEBUG", so the config symbol can just be dropped.

To compile this driver as a module, choose M here:
the module will be called nfit.

help
Enabling this option causes the nfit driver to dump the
input and output buffers of _DSM operations on the ACPI0012
device and its children. This can be very verbose, so leave
it disabled unless you are debugging a hardware / firmware
issue.
