mtd: nand: raw: atmel: Remove redundant PMECC probe
Always probing pmecc in the generic nand controller probe function and
bailing out if pmecc is missing, prevents the driver to be usable for
SoCs which do not have a pmecc hardware ecc engine like older sam9 SoCs,
for example at91sam9g20. Tested on sam9x60 that the call, which the
comment was moved to, is sufficient to probe the pmecc.
