rockchip: defconfig: puma-rk3399: enable RK3399 efuse driver
With everything in place (i.e. the new efuse driver, the clk-support
for the non-secure efuse block, and the board-specific functions to
derive 'serial#' from the cpu-id within the efuses), enable this in
the RK3399-Q7 defconfig.

Cover-letter:
rockchip: Add a read-only efuse driver for the RK3399 (and derive serial# from fuses on the RK3399-Q7)
As the RK3399-Q7 (Puma) differs from our previous modules in how we
can force an external boot (on the RK3399-Q7 this holds the eMMC and
SPI in reset, until an external signal is removed) through the 'BIOS
disable'-signal of the Qseven specification, we can't derive the
unique board id reliably from the eMMC's unique id.
Instead, for the RK3399-Q7, we rely on the efuse block of the RK3399
and use the (assumed to be unique) cpu_id region.
This patch-series adds the required infrastructure and switches the
RK3399-Q7 (puma_rk3399) over to this new infrastructure:
- adds a rockchip-efuse driver as a misc-device (and permits requests
for the clock gate listed in the DTS for the efuse node)
- ports the CRC32-based 'serial#' derivation over from Linux
- exposes the complete cpu_id field through 'cpuid#'
