can: mcp251xfd: mcp251xfd_chip_softreset_check(): wait for OSC ready before accessing chip

This patch changes the order of reading the Mode and Oscillator Ready
bits.

Instead of reading the Mode of the chip directly after reset, first
wait for the oscillator to get ready and the chip to fully start up.
Read the Mode after this.
