The wcove USB Type-C driver is currently being flooded with
interrupts that are not targeted to it. The reason for that
is because all CHRG first level interrupts are mapped to it.
This fixes the issue by introducing separate irq for the
usbc device, and mapping only USB Type-C PHY interrupts to
it.

The Intel Whiskey Cove PMIC includes several function units, e.g.
ADC, thermal, USB Type-C, GPIO, etc. The corresponding device has
to be created in the mfd driver(intel_soc_pmic_bxtwc.c). This change
adds the USB Type-c device.

The call to kstrtoul() will corrupt memory on 64 bit systems because an
int is 4 bytes and a long is 8.
Also it's not a good idea to let users trigger a dev_err() because it
just ends up flooding /var/log/messages so I removed the printk.

Add MFD core driver for Intel Broxton Whiskey Cove PMIC,
which is specially accessed by hardware IPC, not a generic
I2C device
