mmc : boot partition is set as a read-write.

There is a case that user directly update boot partition through mmcblk0boot0,1.
However, the current boot partition is set as a read-only.
I suggest that boot partition is set as a read-write if there is no
reason that it should be read-only.

static int mmc_blk_alloc_parts(struct mmc_card *card, struct mmc_blk_data *md)
{
int ret = 0;

if (!mmc_card_mmc(card))
return 0;

if (card->ext_csd.boot_size) {
ret = mmc_blk_alloc_part(card, md, EXT_CSD_PART_CONFIG_ACC_BOOT0,
card->ext_csd.boot_size >> 9,
false,
"boot0");
if (ret)
return ret;
ret = mmc_blk_alloc_part(card, md, EXT_CSD_PART_CONFIG_ACC_BOOT1,
card->ext_csd.boot_size >> 9,
false,
"boot1");
if (ret)
return ret;
}
}

Thanks.
