can: m_can: Call the RAM init directly from m_can_chip_config

Browse source

[ Upstream commit eaacfeaca7 ]

When we try to access the mcan message ram addresses during the probe,
hclk is gated by any other drivers or disabled, because of that probe
gets failed.

Move the mram init functionality to mcan chip config called by
m_can_start from mcan open function, by that time clocks are
enabled.
