[PATCH] pwm: atmel-hlcdc: add errata handling for sama5d4

[Nicolas Ferre]

sama5d4 SoC also has an errata on the HLCDC PWM. It is the same as the sama5d3
that is forbidding the use of div1 prescaler.

The "atmel,sama5d4-hlcdc" compatible string is not yet documented in
the atmel-hlcdc MFD driver binding, but this shouldn't hurt, so

Yes, I'll document it when I'm submitting your patches that add the
compatibility strings to the drivers/mfd/atmel-hlcdc.c. (with
atmel,at91sam9x5-hlcdc as well).

I'll take your word on it that this will be documented, so I've applied
this.
