Subject: [PATCH v2 34/41] cpufreq: s3c24xx: split out registers

From: Arnd Bergmann <arnd@...db.de>

Each of the cpufreq drivers uses a fixed set of register
bits, copy those definitions into the drivers to avoid
including mach/regs-clock.h.

Signed-off-by: Arnd Bergmann <arnd@...db.de>
[krzk: Fix build by copying also S3C2410_LOCKTIME]
Signed-off-by: Krzysztof Kozlowski <krzk@...nel.org>

---

Changes since v1:
1. Copy also S3C2410_LOCKTIME to the driver.
