Remove dependency on __sdidinit member of struct _reent to check
object initialization. Like __sdidinit, the __cleanup member of
struct _reent is initialized in the __sinit() function. Checking
initialization against __cleanup serves the same purpose and will
reduce overhead in the __sfp() function in a follow up patch.
This patch is similar the arm one committed recently.

Likewise.
Semihosting v2 changes are documented here:

to add more extensions in the future.
