mtd: m25p80: assign default read command

drivers: mtd: m25p80: convert "bool" read check into an enum

We converted the boolean 'fast_read' property to become an enum
'flash_read', but at the same time, we changed the conditional path so
that it doesn't choose a default value in some cases (technically, we
choose the correct default simply by virtue of devm_kzalloc(), which
zeroes this out to be a NORMAL read operation, but still...).

Fix this by setting a default for the 'else' clause.
