ARM: dts: rockchip: Use mount-matrix on rk3188-bqedison2qc

'rotation-matrix' is not a valid property.

Use the documented 'mount-matrix' property instead.

This fixes the following dt-schema warning:

accelerometer@29 (st,lis3de): 'rotation-matrix' does not match any of the
regexes: '^pinctrl-[0-9]+$'

accelerometer@29 (st,lis3de): rotation-matrix:
b'1\x000\x000\x000\x00-1\x000\x000\x000\x001\x00' is not of type 'object',
'integer', 'array', 'boolean', 'null'
