Penny Zheng 59dc61df5b kernel: Enable new LTS 5.4.3 on AArch64 ...

Linux has embraced another LTS kernel version v5.4.x.
If we, AArch64, update stable guest kernel version
to v5.4.x, we could get rid of huge chunkes of backport
patches under patches/4.19.x/.
Except following configs are penny-defined turned on/off,
all the other are sort of `built-in` defined or inherited
from v4.19.x.
1. CONFIG_IO_URING = y
This option enables support for the io_uring interface.
2. CONFIG_RODATA_FULL_DEFAULT_ENABLED = n
Apply read-only attributes of VM areas to the linear
alias of the backing pages as well.
3. CONFIG_ARM64_TAGGED_ADDR_ABI = n
When this option is enabled, user applications can opt in to
a relaxed ABI allow virtual tagged addresses to be passed to
system calls as pointer arguments.
4. CONFIG_ARM64_PTR_AUTH = n
Pointer authentication provides instructions for signing and
authenticating pointers against secret keys, which can be used to
mitigate Return Oriented Programming (ROP) and other attacks.

Fixes: #882
