ASoC: skl: Fix kernel warning due to zero NHTL entry
I got the following kernel warning when loading snd-soc-skl module on
Dell Latitude 7270 laptop:
memremap attempted on mixed range 0x0000000000000000 size: 0x0
WARNING: CPU: 0 PID: 484 at kernel/memremap.c:98 memremap+0x8a/0x180
Call Trace:
skl_nhlt_init+0x82/0xf0 [snd_soc_skl]
skl_probe+0x2ee/0x7c0 [snd_soc_skl]
....
It seems that the machine doesn't support the SKL DSP gives the empty
NHLT entry, and it triggers the warning. For avoiding it, let do the
zero check before calling memremap().
