accel/amdxdna: Declare npu device profile as static variables

Declare the variables as static to fix the sparse warnings:
symbol 'npu5_dev_priv' was not declared. Should it be static?
symbol 'npu1_dev_priv' was not declared. Should it be static?
symbol 'npu4_dev_priv' was not declared. Should it be static?
symbol 'npu2_dev_priv' was not declared. Should it be static?

Fixes: 8c9ff1b ("accel/amdxdna: Add a new driver for AMD AI Engine")
