In preparation to enabling -Wimplicit-fallthrough, mark switch
cases where we are expecting to fall through.

This patch fixes the following warnings:

drivers/mtd/lpddr/lpddr_cmds.c: In function ‘chip_ready’:
drivers/mtd/lpddr/lpddr_cmds.c:319:6: warning: this statement may fall through [-Wimplicit-fallthrough=]
   if (mode == FL_READY && chip->oldstate == FL_READY)
      ^
drivers/mtd/lpddr/lpddr_cmds.c:322:2: note: here
  default:
  ^~~~~~~

Warning level 3 was used: -Wimplicit-fallthrough=3

This patch is part of the ongoing efforts to enabling
-Wimplicit-fallthrough.

You sent me that one twice, is that expected? Is this a new version,

You sent me that one twice, is that expected? Is this a new version,
and in that case, what has changed?

In preparation to enabling -Wimplicit-fallthrough, mark switch
cases where we are expecting to fall through.

This patch fixes the following warning:

drivers/mtd/lpddr/lpddr_cmds.c: In function ‘chip_ready’:
drivers/mtd/lpddr/lpddr_cmds.c:319:6: warning: this statement may fall through [-Wimplicit-fallthrough=]
   if (mode == FL_READY && chip->oldstate == FL_READY)
      ^
drivers/mtd/lpddr/lpddr_cmds.c:322:2: note: here
  default:
  ^~~~~~~

Warning level 3 was used: -Wimplicit-fallthrough=3

This patch is part of the ongoing efforts to enable
-Wimplicit-fallthrough.
