ASoC: Intel: avs: Fix build error on arc, m68k and sparc

On some platforms (i.e. arc, m68k and sparc) __fls returns an int (while
on most platforms it returns an unsigned long). This triggers a format
warning on these few platforms as the driver uses %ld to print a warning.

So explicitly cast the return value to unsigned long to make the warning
go away (and so fix allmodconfig build on the affected architectures).
