Thomas Zimmermann 479d89c91f fbdev/hecubafb: Generate deferred I/O ops
Use the existing generator macros to create deferred-I/O helpers
for hecubafb and set them in the fb_ops structure. Functions
for damage handling on memory ranges and areas are provided by
the driver.

Hecubafb's implementation of fb_write writes to system memory,
so the generated code can use the respective helper internally.
This also fixes a long-standing bug where fb_write returned an
errno code instead of the number of written bytes. See the commit
message of commit 921b7383f3 ("fbdev: Return number of bytes
read or written") for more details.
