[PATCH 2/3] drivers: mmc: uclass: Set removable flag based on device tree property

[Balaji Selvanathan]

The block device removable flag should reflect whether the MMC
device is physically removable (SD card) or soldered (eMMC). This
information is specified in the device tree via the "non-removable"
property and stored in the MMC_CAP_NONREMOVABLE capability flag.

Update the removable flag in the block device descriptor after
successful MMC initialization to properly reflect the device's
removable status. This allows the block layer and upper layers to
distinguish between eMMC and SD cards for appropriate handling.

The default removable=1 is set in mmc_bind(), and this change
overrides it only for non-removable devices after confirming
successful initialization.
