i2c: xlr: add support for Sigma Designs controller variant
Sigma Designs chips use a variant of this controller with the following
differences:
- The BUSY bit in the STATUS register is inverted
- Bit 8 of the CONFIG register must be set
- The controller can generate interrupts
This patch adds support for the first two of these. It also calculates
and sets the correct clock divisor if a clk is provided. The bus
frequency is optionally speficied in the device tree node.
