can: mcp251xfd: mcp251xfd_chip_wait_for_osc_ready(): prepare for PLL support

The function mcp251xfd_chip_wait_for_osc_ready() polls the Oscillator
Control Register for the oscillator to get ready. By passing the
appropriate parameters (osc_reference and osc_mask) it can also poll
for PLL ready.

This patch adjusts the error message if the Oscillator and/or PLL fail
to get ready.
