Subject: ARM: sa1100: register clocks early

From: Russell King <[email protected]>

commit 198b51e8a6a31d3a6f8e9dd9cade3635d0291f26 upstream.

Since we switched to use pxa_timer, we need to provide the OSTIMER0 clock. However, as the clock is initialised early, we need to provide the clock early as well, so that pxa_timer can find it. Adding the clock to the clkdev table at core_initcall() time is way too late.

Move the initialisation earlier.

Fixes ee3a4020f7c9 ("ARM: 8250/1: sa1100: provide OSTIMER0 clock for pxa_timer")
