82b838f8dd pinctrl: k210: Fix inverted IE and OE for I2C
I2C and SCCB previously shared defaults. However, SCCB needs OE_INV and
IE_INV set, but I2C cannot have those bits set. This adds a separate
default for SCCB.

7224d5ccf8 pinctrl: Add support for Kendryte K210 FPIOA
The Fully-Programmable Input/Output Array (FPIOA) device controls pin
multiplexing on the K210. The FPIOA can remap any supported function to any
multifunctional IO pin. It can also perform basic GPIO functions, such as
reading the current value of a pin. However, GPIO functionality remains
largely unimplemented (in favor of the dedicated GPIO peripherals).
