In a systems that provide strings.h and it is included
together with sbi_bitops.h the compilation error appears.
The ffs() and fls() are provided by strings.h

Using "void *" in arithmetic causes errors with strict compiler settings:
"error: pointer of type 'void *' used in arithmetic [-Werror=pointer-arith]"
Avoid these by calculating on "char *" where 1-byte data size is assumed.

Generic mdelay() and udelay() functions can be provided by the
sbi_timer framework if timer frequency is available in the timer
instance provided by the platform support or timer driver.
This patch adds timer frequency (timer_freq) member in the
struct sbi_timer_device for above purpose.

We simplify MTIMER synchronization as follows:
1) Detect MTIMER devices with unique (or non-shared) MTIME
register at boot-time
2) Select first MTIMER device with no associated HART as our
reference MTIMER device
3) Only synchronize MTIMER devices with unique (or non-shared)
MTIME register using reference MTIMER device
4) Directly update the MTIME register at time of synchronization
because MTIME is a read/write register.

We extend the ACLINT library to support separate base addresses
for MTIME and MTIMECMP registers.

We add common ACLINT MTIMER library similar to the CLINT library
so that OpenSBI platforms can use it.
