cmd: cpu: add release subcommand
Add a new subcommand 'release' to bring up a core to run baremetal
and RTOS applications.
For example on i.MX8M Plus EVK, release the LAST core to run a RTOS
application, passing the sequence number of the CPU core to release,
here it is 3:
u-boot=> cpu list
0: cpu@0 NXP i.MX8MP Rev1.1 A53 at 1200 MHz at 31C
1: cpu@1 NXP i.MX8MP Rev1.1 A53 at 1200 MHz at 30C
2: cpu@2 NXP i.MX8MP Rev1.1 A53 at 1200 MHz at 31C
3: cpu@3 NXP i.MX8MP Rev1.1 A53 at 1200 MHz at 31C
u-boot=> load mmc 1:2 c0000000 /hello_world.bin
66008 bytes read in 5 ms (12.6 MiB/s)
u-boot=> dcache flush; icache flush
u-boot=> cpu release 3 c0000000
Released CPU core (mpidr: 0x3) to address 0xc0000000
