Many hwmon drivers use jiffies but omit the inclusion of the header
file. Fix that, and also fix one driver which was including the header
file but didn't need it.

INA220 is register compatible to INA219, and INA230 is register compatible to
INA226, so all we need to do is to add name aliases for those two chips.

Replace per-device initialization and per-device calculation code with
per-device configuration data, which is then used to configure the chip and
perform calculations based on that data.

This patch reduces code size by more than 400 bytes on x86_64.

The driver uses be16_to_cpu and cpu_to_be16 to convert data in SMBus word
operations from chip to host byte order. However, the data passed from and to
the SMBus word API functions is in host byte order, not in chip byte order.
Conversion should therefore use swab16 instead of be16 to change the byte order.

Replace driver internal word conversion functions with SMBus API functions to
solve the problem.
