rtc: mpfs: Remove printing of stray CR

Browse Source 
During boot, the driver prints out a stray carriage return character.
Remove it, together with the preceding space character.

While at it, change prescaler to "unsigned long", as returned by
clk_get_rate(), to avoid truncating very large clock rates, and update
the format specifiers.
