Commit 55ed51fff224 ("{tty: serial, nand: onenand}: samsung: rename to
fix build warning") has changed the samsung.c driver to be
samsung_mtd.c in order to avoid a conflict in module names with the
tty driver.
Since the *_mtd suffix is very undescriptive, rename it to
onenand_samsung.c, following the folder's convention. Same will be
applied to the omap2 onenand driver.

Print size_t as %zu to fix -Wformat warnings when compiling on 64-bit
platform (e.g. with COMPILE_TEST):
drivers/mtd/nand/onenand/samsung_mtd.c: In function ‘s5pc110_read_bufferram’:
drivers/mtd/nand/onenand/samsung_mtd.c:661:16: warning:
format ‘%d’ expects argument of type ‘int’, but argument 3 has type ‘size_t {aka long unsigned int}’ [-Wformat=]
dev_err(dev, "Couldn't map a %d byte buffer for DMA\n", count);

The __iomem memory should be copied with memcpy_fromio. This fixes
Sparse warnings like:

Any arm config which has 'CONFIG_MTD_ONENAND_SAMSUNG=m' and
'CONFIG_SERIAL_SAMSUNG=m' gives a build warning:
warning: same module names found:
drivers/tty/serial/samsung.ko
drivers/mtd/nand/onenand/samsung.ko
Rename both drivers/tty/serial/samsung.c to
drivers/tty/serial/samsung_tty.c and drivers/mtd/nand/onenand/samsung.c
drivers/mtd/nand/onenand/samsung_mtd.c to fix the warning.
