mmc: dt: Add reg/interrupts to mmc.txt for clarity. 

Even though these aren't parsed by the MMC driver, make clear that
they're required by the OF core.  (Also, a few typo fixes.)

@ -2,13 +2,17 @@ These properties are common to multiple MMC host controllers. Any host
that requires the respective functionality should implement them using
these definitions.
Interpreted by the OF core:
- reg: Registers location and length.
- interrupts: Interrupts used by the MMC controller.
Required properties:
- bus-width: Number of data lines, can be <1>, <4>, or <8>
Optional properties:
- cd-gpios : Specify GPIOs for card detection, see gpio binding
- wp-gpios : Specify GPIOs for write protection, see gpio binding
- cd-inverted: when present, polarity on the wp gpio line is inverted
- cd-gpios: Specify GPIOs for card detection, see gpio binding
- wp-gpios: Specify GPIOs for write protection, see gpio binding
- cd-inverted: when present, polarity on the cd gpio line is inverted
- wp-inverted: when present, polarity on the wp gpio line is inverted
- non-removable: non-removable slot (like eMMC)
- max-frequency: maximum operating clock frequency
