staging: csr: remove CsrStrNcpy 

A few other functions were using it, but no one was calling them, so
remove them as well:
	CsrUtf8StrNCpy()
	CsrUtf8StrNCpyZero()
	CsrUtf8StringConcatenateTexts()

*******************************************************************************/
u8 *CsrUtf8StrTruncate(u8 *target, size_t count);
/*******************************************************************************
NAME
CsrUtf8StrNCpy
DESCRIPTION
Copies the first count bytes of source to target. If the end of the
source UTF-8 string (which is signaled by a null-character) is found
before count bytes have been copied, target is padded with null
characters until a total of count bytes have been written to it.
No null-character is implicitly appended to the end of target, so target
will only be null-terminated if the length of the UTF-8 string in source
is less than count.
PARAMETERS
target - Pointer to the target memory where the content is to be copied.
source - UTF-8 string to be copied.
count - Maximum number of bytes to be written to target.
RETURNS
Returns target
*******************************************************************************/
u8 *CsrUtf8StrNCpy(u8 *target, const u8 *source, size_t count);
/*******************************************************************************
NAME
CsrUtf8StrNCpyZero
DESCRIPTION
Equivalent to CsrUtf8StrNCpy, but if the length of source is equal to or
greater than count the target string is truncated on a UTF-8 character
boundary by writing a null character somewhere in the range
target[count - 4]:target[count - 1], leaving the target string
unconditionally null terminated in all cases.
Please note that if the length of source is shorter than count, no
truncation will be applied, and the target string will be a one to one
copy of source.
PARAMETERS
target - Pointer to the target memory where the content is to be copied.
source - UTF-8 string to be copied.
count - Maximum number of bytes to be written to target.
RETURNS
Returns target
