[svd_rs, svd_parser] Differentiation between Arrays and Lists

[Jatsekku]

According to documentation, there are actually two sequential types for some of child elements, which can be created by using placeholder:
[%s] - for arrays, in such case <dimIndex></dimIndex> should not be used.
%s - for lists, in that case <dimIndex></dimIndex> can be used.

Peripherals - for some reason they advise to not create peripheral list, only arrays:

dimIndex Do not define on peripheral level. By default, is an integer value starting at 0.

name The string identifies the peripheral. Peripheral names are required to be unique for a device. The name needs to be an ANSI C identifier to generate the header file. You can use the placeholder [%s] to create arrays.

Registers and Clusters - both can be used:

dimIndex Specify the substrings that replaces the %s placeholder within name and displayName. By default, the index is a decimal value starting with 0 for the first register. dimIndex should not be used together with the placeholder [%s], but rather with %s.

name String to identify the register. Register names are required to be unique within the scope of a peripheral. You can use the placeholder %s, which is replaced by the dimIndex substring. Use the placeholder [%s] only at the end of the identifier to generate arrays in the header file. The placeholder [%s] cannot be used together with dimIndex.
