handling.
- Extended PWRCTL/PMU APIs to support querying clock frequency during very
early boot, prior to bus attach.
- Implement generic PMU-based calculation of UART rclk values.
- Replaced use of static frequency tables (bcm_socinfo) with
runtime-determined values.

This adds support for performing platform_reset() on all supported
devices, using early boot enumeration of chipc capabilities and
available cores.
- Added Broadcom-specific MIPS CP0 register definitions used by
BCM4785-specific reset handling.
- Added a bcm_platform structure for tracking chipc/pmu/cfe platform
data.
- Extended the BCMA EROM API to support early boot lookup of core info
(including port/region mappings).
- Extended platform_reset() to support PMU, PMU+AOB, and non-PMU
devices.

Relying on the boot loader console configuration allows us to use a
common set of device hints for all SENTRY5 devices.

The delta between SENTRY5 and BCM was already small due to BCM being
derived from SENTRY5; re-integrating the two avoids the maintenance
overhead of keeping them both in sync with bhnd(4) changes.
- Re-integrate minor SENTRY5 deltas in bcm_machdep.c
- Modify uart_cpu_chipc to allow specifying UART debug/console flags via
kenv and device hints.
- Switch SENTRY5 to std.broadcom
- Enabled CFI flash support for SENTRY5

Relies on BHND(4) driver.
There files contains machine-dependent code for Broadcom MIPS processor and
provide UART driver.
This is a work in progress; it and the current bhnd code is enough to boot
on the ASUS RT-N16 and RT-N53 platforms.
