* arch/arm/src/lc823450: Fix up_enable_irq() timing for I2S.
In previous commit, I2S IRQ might be sometimes assigned to CPU1
when CONFIG_SMP=y. This change fixes this issue.
Signed-off-by: Masayuki Ishikawa <Masayuki.Ishikawa@jp.sony.com>
* arch/arm/src/lc823450: Refactor timer driver.
Introduce lc823450_timer.h and move lc823450_timerisr.c to
lc823450_timer.c Add MTM timer APIs for DVFS. Introduce
up_rtc_gettime() for CONFIG_RTC_HIRES.

* arch/arm/src/lc823450: Introduce idle time calculation in DVFS
Also, DVFS autonomous mode based on CPU idle time is supported.
NOTE: voltage control is still disabled.

* configs/lc823450-xgevk: Update defconfigs
Enable RTC_HIRES instead of RTC_DATETIME (audio/rndis)
Disable TCP_WRITE_BUFFERS and change SCHED_LPWORKPRIORITY (rndis)

* configs/lc823450-xgevk: Update README.txt
