[PATCH 3/3] mtd: spi-nor: macronix: Move macronix_nor_default_init logic to macronix_nor_late_init

[Cheng Ming Lin <linchengming884@gmail.com>]

From: Cheng Ming Lin <chengminglin@mxic.com.tw>

Remove macronix_nor_default_init and move its functionality to
macronix_nor_late_init to ensure proper quad_enable initialization.

For MX25L3255E, SFDP follows JESD216, which does not include the Quad
Enable bit Requirements field in its version. When the size field is
removed, manufacturer->fixups->default_init hook is not executed, causing
params->quad_enable not being overwritten with the intended function.
Consequently, it remains as the default spi_nor_sr2_bit1_quad_enable.

By moving quad_enable setup from default_init to late_init, quad_enable
is correctly assigned after spi_nor_init_params, regardless of the size
field removal.

Additionally, according to spi-nor/core.h, quad_enable is more
appropriately placed in late_init, as older SFDP versions did not define
the Quad Enable bit Requirements. This change removes default_init and
moves quad_enable handling to late_init accordingly.
