A one-bit wide bit-field can take only the values 0 and -1. Clang 16
introduced a warning that "implicit truncation from 'int' to a one-bit
wide bit-field changes value from 1 to -1". Fix by using c99 bool.

bus_get/set_resource methods are implemented in child device (iicbus).
As their implementation with bus_generic_rl_get/set calls do not
recurse up the tree, the versions in ig4 are never called.

Revert r336326.

In testing on a Dell Latitude 7480, having ig4.ko loaded during a
suspend caused the system to hang. It turns out that ig4iic_intr() was
being called after the device entered D3, and entered an infinite loop
because a read of the I2C status register returned all ones, causing us
to attempt to read a byte from the data buffer until one of the status
bits clears. This occured because ig4iic_pci0 shares an interrupt with
the VGA device on this laptop, so ig4iic_intr() gets called even when
there is no work to do. This is exactly the problem fixed by r342170,
which resolves the hang for me and allows suspend/resume to work with
ig4.ko loaded. So, re-enable autoloading of ig4.ko in the hope that
r342170 resolves the problem universally.
