We should prefer accessing CSRs using their CSR numbers because:
1. It compiles fine with older toolchains.
2. We can use latest CSR names in #define macro names of CSR numbers
as-per RISC-V spec.
3. We can access newly added CSRs even if toolchain does not recognize
newly addes CSRs by name.

This patch adds SCAUSE interrupt flag and SCAUSE interrupt related
defines to asm/csr.h. We also use these defines in kernel/irq.c and
express SIE/SIP flags in-terms of SCAUSE interrupt causes.

The spacing between macro name and value is not consistent in
asm/csr.h. This patch beautifies asm/csr.h by using tabs to align
macro values instead of spaces.

satp is the name used by the current privileged spec 1.10, use it
instead of the old name. The most recent release binutils release
(2.29) doesn't know about the satp name yet, so stick to the name from
the previous privileged ISA release and comment on the fact.

This patch contains code that is more specific to the RISC-V ISA than it
is to Linux. It contains string and math operations, C wrappers for
various assembly instructions, stack walking code, and uaccess.
