Additional info. I took v4.4.16 and add the following to the default
x86_64_defconfig:
+CONFIG_MMIOTRACE=y
+CONFIG_SERIAL_8250_DW=y
+CONFIG_MFD_INTEL_LPSS=y
+CONFIG_MFD_INTEL_LPSS_PCI=y

The problem is still reproduced.
I can't take earlier kernels because the mentioned driver (intel-lpss)
was introduced in v4.4.
