iicbus/mux/pca954x: add support for PCA9546 I2C Switch
Add support for the 4 channel I2C switch from NXP by adding a new description struct and the list entries. Compared to x=[2345] which require code to support the INT, for this one no further changes are needed. Tested on: WHLE-LS1088A using a SPF+ MFC after: 1 week Reviewed by: imp Differential Revision: https://reviews.freebsd.org/D44009
