bpf: move the bpf syscall sysctl table to bpf module
bb93730 
Aggregating the code of the feature in the code file of the feature
itself can improve readability and reduce merge conflicts. So move
the bpf syscall sysctl table to kernel/bpf/syscall.c

bpf, arm64: bpf trampoline for arm64
47ef389 
Add bpf trampoline support for arm64. Most of the logic is the same as
x86.

fentry before bpf trampoline hooked:
 mov x9, x30
 nop

fentry after bpf trampoline hooked:
 mov x9, x30
 bl  <bpf_trampoline>

Tested on qemu, result:
 #55 fentry_fexit:OK

 #59 fexit_stress:OK
 #60 fexit_test:OK

It happens because of play_dma_data/capture_dma_data pointers are NULL.
Current implementation assigns these pointers at snd_soc_dai_driver
startup() callback and reset them back to NULL at shutdown(). But
soc_pcm_open() sequence uses DMA pointers in dmaengine_pcm_open()
before snd_soc_dai_driver startup().
Most generic DMA capable I2S drivers use snd_soc_dai_driver probe()
callback to init DMA pointers only once at probe. So move DMA init
to dw_i2s_dai_probe and drop shutdown() and startup() callbacks.
