busy_loop() returns negative error code, thus change err variable
from u32 to int to properly propagate correct error code.Also remove unneeded initialization for err and i variables.

SFI provides a series of tables. These describe the platform devices present
including SPI and I²C devices, as well as various sensors, keypads and other
glue as well as interfaces provided via the SCU IPC mechanism (intel_scu_ipc.c)This patch is a merge of the core elements and relevant fixes from the
Intel development code by Feng, Alek, myself into a single coherent patch
for upstream submission.It provides the needed infrastructure to register I2C, SPI and platform devices
described by the tables, as well as handlers for some of the hardware already
supported in kernel. The 0.8 firmware also provides GPIO tables.Devices are created at boot time or if they are SCU dependant at the point an
SCU is discovered. The existing Linux device mechanisms will then handle the
device binding. At an abstract level this is an SFI to Linux device translator.Device/platform specific setup/glue is in this file. This is done so that the
drivers for the generic I²C and SPI bus devices remain cross platform as they
should.(Updated from RFC version to correct the emc1403 name used by the firmware
and a wrongly used #define)Signed-off-by: Alek Du

We need to include the SFI headers. This is fine as the SCU is only
relevant to x86 platforms with SFI.Fixes the -next warning report.

The stack buffer for IPC messages was 16 bytes, limiting messages to a
size of 4 (each message is 32 bit).
However, the touch screen driver is trying to send messages of size 5....(AC: Set to 20 bytes having checked the max size allowed)
