rtc: mpfs: Remove printing of stray CR
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.
