Since commit 657eee7 (media: coda: use genalloc API) the following build
error happens with imx_v4_v5_defconfig:
drivers/built-in.o: In function 'coda_remove':
clk-composite.c:(.text+0x112180): undefined reference to 'gen_pool_free'
drivers/built-in.o: In function 'coda_probe':
clk-composite.c:(.text+0x112310): undefined reference to 'of_get_named_gen_pool'
clk-composite.c:(.text+0x1123f4): undefined reference to 'gen_pool_alloc'
clk-composite.c:(.text+0x11240c): undefined reference to 'gen_pool_virt_to_phys'
clk-composite.c:(.text+0x112458): undefined reference to 'dev_get_gen_pool'
Select GENERIC_ALLOCATOR and get rid of the custom IRAM_ALLOC.

From: Fabio Estevam <fabio.estevam@freescale.com>
commit 6cd2c7db4 (videomode: videomode_from_timing work) changed the name of
the function from videomode_from_timing() to videomode_from_timings().
commit 32ed6ef1 (videomode: create enum for videomode's display flags) changed
the 'data_flags' field in videomode structure to 'flags'
Adapt to these changes in order to fix the following errors:
drivers/video/mxsfb.c:761:3: error: too many arguments to function 'videomode_from_timing'
drivers/video/mxsfb.c:761:7: error: void value not ignored as it ought to be
drivers/video/mxsfb.c:768:9: error: 'struct videomode' has no member named 'data_flags'
drivers/video/mxsfb.c:770:9: error: 'struct videomode' has no member named 'data_flags'
Also, select VIDEOMODE_HELPER instead of OF_VIDEOMODE, as this one is
deprecated.
