can: m_can: Call the RAM init directly from m_can_chip_config

[ Upstream commit eaacfeaca7ad0804b9a6eff7afeba93a87db7638 ]

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.
