Tony Lindgren 03522d73a4 bus: ti-sysc: Flush posted write on enable before reset ...

[ Upstream commit 34539b442b ]

The am335x devices started producing boot errors for resetting musb module
in because of subtle timing changes:

Unhandled fault: external abort on non-linefetch (0x1008)
...
sysc_poll_reset_sysconfig from sysc_reset+0x109/0x12
sysc_reset from sysc_probe+0xa99/0xeb0
...

The fix is to flush posted write after enable before reset during
probe. Note that some devices also need to specify the delay after enable
with ti,sysc-delay-us, but this is not needed for musb on am335x based on
my tests.
