arm64: dts: librem5-devkit: add lsm9ds1 mount matrix

The IMU chip on the librem5-devkit is not mounted at the "natural" place
that would match normal phone orientation (see the documentation for the
details about what that is).

Since the lsm9ds1 driver supports providing a mount matrix, we can describe
the orientation on the board in the dts:

Create a right-handed coordinate system (x * -1; see the datasheet for the
axis) and rotate 180 degrees around the y axis because the device sits on
the back side from the display.

GPIO_ACTIVE_x flags are not correct in the context of interrupt flags.
These are simple defines so they could be used in DTS but they will not
have the same meaning:
1. GPIO_ACTIVE_HIGH = 0 = IRQ_TYPE_NONE
2. GPIO_ACTIVE_LOW = 1 = IRQ_TYPE_EDGE_RISING

Correct the interrupt flags, assuming the author of the code wanted same
logical behavior behind the name "ACTIVE_xxx", this is:
