dfu: make data buffer size configurable
Dfu transfer uses a buffer before writing data to the raw storage device. Make the size (in bytes) of this buffer configurable through environment variable "dfu_bufsiz". Defaut value is configurable through CONFIG_SYS_DFU_DATA_BUF_SIZE Signed-off-by: Heiko Schocher <hs@denx.de> Cc: Pantelis Antoniou <panto@antoniou-consulting.com> Cc: Tom Rini <trini@ti.com> Cc: Lukasz Majewski <l.majewski@samsung.com> Cc: Kyungmin Park <kyungmin.park@samsung.com> Cc: Marek Vasut <marex@denx.de> Cc: Wolfgang Denk <wd@denx.de> Acked-by: Tom Rini <trini@ti.com>
