[PATCH v4 05/28] mtd: spi-nor: Init flags before manufacturer late_init() hooks

Current init order is:
- The manufacturer-wide late_init() hook is called.
- The core initializes some chip flags
- The chip specific late_init() hook is called.

This does not seem very consistent since both late_init() may need to
touch flags, which is then not working as expected since the order is a
bit inconsistent. Moving spi_nor_init_flags() earlier, right before the
manufacturer late_init() call, ensures the hook sees the flags after
their initialization, and can therefore apply changes to them.

Since spi_nor_init_flags() only reads ->info->flags and DT properties,
it does not depend on anything a late_init() hook produces. On the other
hand, no manufacturer late_init() hook currently touches any output of
spi_nor_init_flags() either. Reordering seems safe™.
