linuxkpi: unbreak linux_i2cbb
This is a joint work with manu.
- fixed conditions in do_i2c_transfer and i2c_transfer as linux_i2cbb
does not set adapter->algo->master_xfer but does set
adapter->algo_data;
- fixed parent bus specification for linux_i2cbb driver module;
- actually implemented iicbb_transfer method;
- added iicbb_pre_xfer and iicbb_post_xfer methods;
- removed unnecessary and harmful delays (and other extra logic) from
iicbb methods as iicbb driver already has them;
- added setting of iicbb speed based on algo_data->udelay, so that iicbb
uses correct delays;

linuxkpi: Add i2c support
Add i2c support to linuxkpi. This is needed by drm-kmod.
For every i2c_adapter added by i2c_add_adapter we add a child to the
device named "lkpi_iic". This child handle the conversion between
Linux i2c_msgs to FreeBSD iic_msgs.
For every i2c_adapter added by i2c_bit_add_bus we add a child to the
device named "lkpi_iicbb". This child handle the conversion between
Linux i2c_msgs to FreeBSD iic_msgs.
With the help of iic(4), this expose the i2c controller to userspace
allowing a user to query DDC information from a monitor.
e.g.: i2c -f /dev/iic0 -a 0x28 -c 128 -d r
will query the standard EDID from the monitor if plugged.
The bitbang part (lkpi_iicbb) isn't tested at all for now as I don't have
compatible hardware (all my hardware have native i2c controller).
Tested on: Intel (SandyBridge, Skylake, ApolloLake)
Tested on: AMD (Picasso, Polaris (amd64 and arm64))
MFC after: 1 month
